Tripropylene glycol

Tripropylene Glycol (TPG) is a colorless, odorless, viscous liquid with excellent hygroscopicity, stability, low volatility and low toxicity. It is fully miscible with water and most organic solvents, and is widely used as a multifunctional intermediate in coatings, cosmetics, fine chemicals, pharmaceuticals and industrial fields.
In coatings and inks, TPG acts as a coalescing agent and high-boiling solvent, which effectively
reduces the film-forming temperature, improves flexibility, gloss and construction performance. It is also an important raw material for polyurethane foam, widely used in building insulation and automotive interiors.

In cosmetics and personal care, TPG serves as a mild humectant and emollient for creams, lotions and essences, locking skin moisture without irritation. It also works as a solvent for active ingredients and fragrances to enhance product performance.

In fine chemicals and pharmaceuticals, TPG is a key intermediate for plasticizers, lubricants and textile auxiliaries, and can be used as a safe pharmaceutical excipient to improve drug solubility and bioavailability. It also functions as a lubricant and antistatic agent in industrial production.

In addition, TPG is widely used in industrial cleaning, antifreeze, heat transfer fluids and rubber processing to improve material properties and processing efficiency. With stable performance and wide applications, TPG is an indispensable high-quality chemical raw material for various industries.

Product Description

Tripropylene Glycol (TPG) is a clear, colorless, nearly odorless liquid with excellent solubility, low volatility, and high boiling point. It is miscible with water and most organic solvents, featuring moderate viscosity and good stability. 

Our TPG is produced with high purity, free of impurities, and complies with industrial-grade standards. It is available in standard 200kg sealed steel drums or plastic barrels, and customizable packaging (IBC tanks, bulk shipments) is offered to meet different client needs. 

The product is stored in cool, dry, well-ventilated warehouses to ensure quality and stability.

Applications and Uses

TPG is a versatile chemical intermediate and solvent widely used across industries. In coatings, inks, and paints, it acts as a co-solvent and film-forming aid, improving flow, leveling, and adhesion. It serves as a key raw material for synthesizing polyesters, polyurethanes,

 and alkyd resins, and functions as a plasticizer in PVC and other polymers. In personal care, it acts as a humectant and viscosity regulator in lotions and creams. Additionally, TPG is used in textile lubricants, cutting oils, hydraulic fluids, cleaning agents, and as a heat transfer fluid,

 making it indispensable in industrial manufacturing and daily chemical production.

The Hansen parameters fall outside the range of the method, so the distance Ra cannot be calculated, and the database holds no solubility measurement to put in its place. Rather than eleven ratings with nothing behind them, we show none. Base the solvent choice on the safety data sheet and on experimental data.

化学家的真实问题

Why does my chromatogram look like a cardiogram?

The baseline jumps ±10 mAU, you see peaks but also „humps" between them. Integration is impossible.

Why Acetonitrile vs Methanol?

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.

常见问题

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=, CAS 24800-44-0) zaczynaj od ACN w gradiencie 5→95% B.

Gradient Problem From The Lab

Optymalizacja nachylenia gradientu (dG)

Your impurities co-elute in a narrow 5-8 min window. The 30 min runtime is too long. How to use Snyder-Dolan LSS for optimisation?

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.

常见问题

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

Rule of thumb: analytes MW10000 (proteins) → pore 1000 Å. For MW= (CAS 24800-44-0) use a standard C18 100 Å column.

Detection Gotcha

48 godzin stracone na niewidoczne piki

Day 1 — I prepared the sample, injected it, baseline flat. Day 2 — I repeated it 6× with different samples. Nothing. Wave check? Professor: "Take a look at the DAD scan". λ_max = 214 nm, and I had 254 nm set.
Lesson learned (Anna K., studentka 2. rok, PW, 2024-11-15):
ALWAYS run a UV scan of an unknown compound BEFORE the method. 254 nm = aromatics only. 210 nm = universal. Time saved: 2 days of work.

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

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?

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.

事后分析 — 真实失败案例 经验教训

真实化学家的失误 — 发生了什么、什么有帮助、要避免什么。

Ghost peaks w ostatnim dniu stability

Dr. Tomasz W., PhD pharmaceutical 2024-08-22 Poziom 4/5
发生了什么：

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.

💡 Lekcja:

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.

Method transfer from Warsaw to Krakow failed

R&D team, 2 sites 2025-09-18 Poziom 5/5
发生了什么：

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.
