Product Description

Ethylene Carbonate (EC, CAS 96-49-1) is an important high-purity organic solvent widely used in the lithium-ion battery industry.

 It has a high dielectric constant, good chemical stability, and strong solubility, making it an essential component in battery electrolytes. 

It appears as a colorless transparent crystal at room temperature and melts into liquid at low heating temperatures. Our EC is produced as battery grade with purity over 99.90%, strict control of moisture, metal ions, and other impurities,

 ensuring stable and consistent quality for industrial use.

EC is mainly used in lithium-ion battery electrolytes, usually mixed with solvents such as DMC, EMC, and DEC to improve ionic conductivity, form stable SEI films, and enhance battery safety, cycle life, and low-temperature performance.

 It is also applied in chemical synthesis, polymer manufacturing, and textile processing as a mild and efficient solvent. In usage, EC is melted and blended evenly with other solvents under dry and sealed conditions to avoid moisture absorption.

 It is widely applied in consumer electronics, new energy vehicles, and energy storage systems. With high safety and stable performance, EC has become an indispensable basic material in modern energy and chemical industries.

Hinweis zu Datenbeschränkungen. Die Sicherheitsinformationen auf dieser Seite dienen nur zur Information und ersetzen kein vollständiges Sicherheitsdatenblatt (SDS). Konsultieren Sie vor der Verwendung des Produkts das aktuelle Sicherheitsdatenblatt des Herstellers sowie die GHS/CLP-Leitlinien. Die CLP-Einstufung bezieht sich auf die reine Bulk-Substanz, nicht auf handelsübliche Zubereitungen.

GHS/CLP-Einstufung — Verordnung (EG) Nr. 1272/2008 + UN GHS Rev. 9 (2021).

⚠ Achtung (Warning)
GHS07 — Reizend / gesundheitsschädlich
GHS07 Reizend / gesundheitsschädlich
GHS08 — Gesundheitsgefahr
GHS08 Gesundheitsgefahr

🚨 Gefahrenhinweise (H)

  • H302 — Gesundheitsschädlich bei Verschlucken.
  • H315 — Verursacht Hautreizungen.
  • H319 — Verursacht schwere Augenreizung.
  • H373 — Kann die Organe schädigen bei längerer oder wiederholter Exposition.

🛡 Sicherheitshinweise (P)

  • P260 — Staub/Rauch/Gas/Nebel/Dampf/Aerosol nicht einatmen.

⚠ Einstufung basierend auf einem Konsens der Quellen (PubChem / Meldungen der Lieferanten) — nicht gegen die harmonisierte Einstufung in Anhang VI (CLP) verifiziert. Der Gefahrenumfang kann breiter sein als die amtliche Einstufung; vor der Verwendung mit dem aktuellen Sicherheitsdatenblatt des Lieferanten verifizieren.

📈 Analytische Statistik (t-Test · RSD · Grubbs · Q-Dixon) ICH Q2

Fügen Sie eine Serie von Messwiederholungen ein (CSV oder eine Zahl pro Zeile). Der Rechner berechnet Mittelwert, Standardabweichung und 95% CI und erkennt Ausreißer (Grubbs + Dixon Q).

Trennzeichen: Komma, Leerzeichen, Tab, Zeilenumbruch. Min. 3 Messungen.
📐 Statistische Formeln
  • x̄ = Σxᵢ / n — arithmetisches Mittel
  • s² = Σ(xᵢ - x̄)² / (n-1) — Stichprobenvarianz
  • s = √s² — Standardabweichung
  • RSD% = (s / x̄) × 100% — relative Standardabweichung
  • CI₉₅ = x̄ ± t(0.05, n-1) × s / √n — Student's t
  • G = |xᵢ - x̄| / s — Grubbs-Test
  • Q = |xsuspect - xnearest| / |xmax - xmin| — Dixon Q-test

Echtes Chemiker-Problem

What is „system suitability" and do I have to do it?

The teacher said „run an SST". You have no idea what that is. The USP method has a checklist — 4 parameters. Which are critical?

Why Acetonitrile vs Methanol?
PropertyAcetonitrile (ACN)Methanol (MeOH)
Viscosity (20°C)0.37 cP0.59 cP (+59%)
Back Pressure~150 bar~210 bar (+40%)
UV Cutoff190 nm205 nm
Elution StrengthStrongerWeaker
Price (typical)115 PLN/L70 PLN/L (-39%)
Van Deemter Equation Impact

H = A + B/u + Cu

Higher viscosity (MeOH) → lower optimal flow rate → longer runtime.

Buffer Selection: Why NH₄HCO₃?
  • Volatile: MS-compatible (evaporates without residue)
  • pH range: 6.5–8.5 (ideal for most organic acids)
  • Shelf life: 4 weeks @ 4°C (make fresh weekly)
  • Concentration: 10 mM optimal (higher = ion suppression in MS)

Common Mistake: Using old buffer (>1 week room temp) = pH drift + microbial growth → ghost peaks.

Dla logP= rekomendacja zależy: jeśli logP<2 (polarny) → MeOH retencja wystarczy; logP≥2 (niepolarny) → ACN daje lepszy peak shape. Dla tej molekuły (MW=88.06, CAS 96-49-1) zaczynaj od ACN w gradiencie 5→95% B.

Source: Snyder LSS Model

ACN: niższa lepkość (mniejsze ciśnienie), UV cutoff 190 nm. MeOH: 40% tańszy, ale wyższe ciśnienie +50 bar i UV cutoff 205 nm. Dla gradientu: ACN preferowany.

Gradient Problem From The Lab

Linearity over a wide range (5 decades)

ICH Q2: 80-120% spec. Your reviewer wants 1 ng/mL to 10 μg/mL (4 decades). How to build 2 calibrations without bias?

Our Gradient Strategy

  • Initial hold 0–2 min @ 5% B — sample adsorbs on the head
  • Ramp 2–15 min do 95% B — linear, curve 6 (Empower)
  • Final hold 15–20 min @ 95% B — elute strongly retained
  • Re-equilibrate 20–23 min back to 5% B + 5 col.volumes

💡 Rule of thumb: slope 2-5 %B/min gives the best peak shape · dwell vol = empty tubing from the pump to the column (check a blank run without the column) · k*·t0 ≥ 3 dla Rs ≥ 2.0.

Snyder-Dolan LSS Model

Log k = log kw − S·φ, gdzie φ = fraction B. Optymalny gradient: Δφ ≈ 0.6–0.8 per 5 t0. Dla kolumny 250×4.6mm @ 1 mL/min → t0 ≈ 2 min → gradient 10–12 min.

Häufig gestellte Fragen

Linear = płynne odklejanie związku od kolumny = lepszy peak shape (Tf < 1.3). Step gradient daje shock waves = artifacts.

Column Choice Dilemma

What is „system suitability" and do I have to do it?

The teacher said „run an SST". You have no idea what that is. The USP method has a checklist — 4 parameters. Which are critical?

Recommended Columns

A

Zorbax Eclipse Plus C18

150×4.6 mm · 3.5 μm · pH 2–9

B

Waters XBridge C18

150×4.6 mm · 3.5 μm · pH 1–12 (high pH)

C

Phenomenex Kinetex C18

100×4.6 mm · 2.6 μm core-shell · fast

Column Lifetime Rules

  • Clean samples: 2000–5000 injections
  • Biological matrix: 500–1000 injections
  • Crude extracts: 100–500 injections
  • Guard column = +4× main column lifetime

Rule of thumb: analytes MW10000 (proteins) → pore 1000 Å. For MW=88.06 (CAS 96-49-1) use a standard C18 100 Å column.

Detection Gotcha

Pressure too high — what next?

Pressure rises to 400 bar (max 300 for this column). The system is blaring an alarm. Do you shut the pump down? Yes/no?

DAD Settings

ParameterValueWhy

Alternative Detectors

  • RID — for compounds without UV absorbance (sugars, polymers). Sensitivity x1000 lower.
  • ELSD — uniwersalny, ale destroys sample (niezgodny z MS).
  • LC-MS/MS — LOD 1 pg, strukturalna potwierdzenie via MRM.
  • CAD — charged aerosol, lepsze od ELSD dla lipid/polar.

Prep Mistakes That Ruined The Run

Why am I not seeing any peaks?

You injected the sample, you wait 23 min and... a flat line. Anxiety is rising.
Lesson learned (Student MSc, UW, 2024-10):
Wavelength 254 nm does not work for most carboxylic acids — use 210 nm.

Sample Prep Protocol

  1. Dissolve 10 mg of sample in 10 mL of mobile phase (initial composition)
  2. Sonikuj 5 min → vortex 30 s
  3. Filtruj 0.22 μm PTFE (nie PVDF — adsorbuje!)
  4. Transfer 1 mL do HPLC vial z septum PTFE/silikon
  5. Przechowuj 4°C max 48h

Why Filter 0.22 μm?

Particles >0.22 μm clog the column inlet frit. Pressure rises +50 bar per 100 injections. Column lifetime drops from 2000 to 500 injections. Filter cost: 2 PLN. Column cost: 1800 PLN.

Echte Pannen von Chemikern — was passiert ist, was geholfen hat und was zu vermeiden ist.

Incorrect integration — publication rejected

Kasia M., PhD Analytical Chemistry, UJ 2025-06-03 Poziom 4/5
Was ist passiert:

Submission to JPBA. Reviewer 2: „Peak at 12.4 min shows manual integration, but baseline slope suggests co-elution". I had to revalidate the whole method. 3 months of delay.

💡 Lekcja:

Manual integration = a red flag for reviewers. Solve CO-ELUTION in methods dev, not in integration. Optimise the gradient instead of force-fitting the peak.

Method transfer from Warsaw to Krakow failed

R&D team, 2 sites 2025-09-18 Poziom 5/5
Was ist passiert:

At first we ran it in the Warsaw lab. Transfer to Kraków: every Rt shifted +0.8 min, Rs borderline at 1.9-2.1. Investigation: buffers from different manufacturers (Merck vs Sigma-Aldrich) differed by 0.2 in pH. 6 weeks of transfer revalidation.

💡 Lekcja:

Transfer requires a SPEC for the buffer (manufacturer, grade, LOT). Not just „NH4HCO3 10 mM pH 7.0". Run a preliminary system suitability on the new instrument before the full transfer.
