Product Description

Diethylene Glycol Butyl Ether Acetate (DBAC) is a high-boiling glycol ether acetate widely used as a solvent and coalescing agent in multiple industrial applications. From a procurement perspective, it is valued for its strong solvency, low volatility, and excellent compatibility with a wide range of resins and organic systems.

In the coatings and ink industries, Diethylene Glycol Butyl Ether Acetate is commonly used as a solvent and film-forming aid, contributing to improved flow, leveling, and surface finish. Its slow evaporation rate helps extend open time and minimize defects such as pinholes and brush marks, making it suitable for high-performance paints, varnishes, and printing inks.

Within industrial and electronic cleaning applications, DBGA is effective in removing oils, greases, and processing residues. Its balanced solvency and low odor profile make it a preferred component in precision cleaning formulations where efficiency and material compatibility are essential.

In addition, Diethylene Glycol Butyl Ether Acetate serves as an important intermediate and formulation component in specialty chemicals, supporting the production of cleaners, coatings additives, and other performance materials.

From a sourcing and supply chain standpoint, high-quality Diethylene Glycol Butyl Ether Acetate offers:

Consistent purity and controlled impurity levels

Stable performance across diverse applications

Excellent compatibility with various resin systems

Reliable bulk supply and flexible packaging options

Real Chemist Problem

What to set on the DAD for an unknown compound?

You do not know λ_max. The DAD covers 200–800 nm. Set it wide or narrow? Use bandwidth 4 or 16 nm?

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.

Frequently Asked Questions

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.

Source: Chromatography Forum

Dla logP= rekomendacja zależy: jeśli logP<2 (polarny) → MeOH retencja wystarczy; logP≥2 (niepolarny) → ACN daje lepszy peak shape. Dla tej molekuły (MW=204.26, CAS 124-17-4) zaczynaj od ACN w gradiencie 5→95% B.

Gradient Problem From The Lab

Ghost peaks w ostatnim dniu stability

Day 90 stability pull. 6 batch × 2 repeats. W próbce widzę duplikaty peaków z poprzedniego dnia. OOS opened. 4 dni investigation. Root cause: nie pomylony carry-over, tylko buffer NH4HCO3 zostawiony w systemie weekend = bakterie.
Lesson learned (Dr. Tomasz W., PhD pharmaceutical, 2024-08-22):
NIGDY nie zostawiaj buforu w systemie >3 dni. Zawsze flush z 80% ACN/20% H2O przed weekendem. Koszt lekcji: 4 dni pracy + 3 batch release delay.

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.

Frequently Asked Questions

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

Heurystyka Snyder: Rt ≈ 2.5·logP + 1.2 min. Dla 2-(2-butoxyethoxy)ethyl acetate (logP=) → szacunkowe Rt=— min. ±30% wariancja zależnie od dead volume i gradient slope. Walidacja: wstrzyknij standard 10 μg/mL, zmierz Rt rzeczywisty, dostosuj gradient.

Heurystyka Snydera: start%B = (logP - 1) × 10. Dla logP=2 → start 10% B. Zawsze z 2 min isocratic hold aby pozwolić próbce zaadsorbować.

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

Frequently Asked Questions

C18 (18 węgli, bardziej lipofilowa) dla logP 0-5. C8 (8 węgli) dla bardzo polarnych (logP <0). C4 dla białek. Twój związek logP~2 → C18.

Source: Phenomenex Knowledge

Rule of thumb: analyty MW10000 (białka) → pore 1000 Å. Dla MW=204.26 (CAS 124-17-4) użyj standardowej kolumny C18 100 Å.

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.

Validation Reality Check

Method transfer from Warsaw to Krakow failed

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.
Lesson learned (R&D team, 2 sites, 2025-09-18):
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.

Prep Mistakes That Ruined The Run

Eksport chromatogramu do raportu

Your boss wants a PNG of the chromatogram for a presentation. You only have ChemStation with a .ch file. How to get from .ch → PNG?

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.

Forensic Fix — real failure stories Lessons learned

Real chemists' mishaps — what happened, what helped, what to avoid.

10 columns in 2 months — wrong filter

Marta K., QC supervisor, pharma company 2025-02-10 Poziom 4/5
What happened:

Q1 audit: column cost +340% vs Q4. QA blamed the lab. Investigation: a new operator was using a 0.45 μm filter instead of 0.22 μm. Microparticles got through the guard and were killing the main columns by the 100th injection.

💡 Lekcja:

The filter SOP must be WRITTEN and checked every batch. 0.22 μm is the standard per USP . Cost of the error: 10 columns × 1800 PLN = 18,000 PLN + audit finding.

Ghost peaks w ostatnim dniu stability

What happened:

Day 90 stability pull. 6 batch × 2 repeats. W próbce widzę duplikaty peaków z poprzedniego dnia. OOS opened. 4 dni investigation. Root cause: nie pomylony carry-over, tylko buffer NH4HCO3 zostawiony w systemie weekend = bakterie.
