الأسئلة الشائعة
What is hydroxypropyl methylcellulose acetate succinate (HPMCAS) commonly used for?
HPMCAS is primarily used as a **pH-dependent polymer** in pharmaceutical formulations, particularly as a **enteric coating agent** for tablets and capsules to protect drug stability in the stomach and release in the intestine.
What is the molecular formula and molecular weight of HPMCAS?
The repeating unit formula is **C₁₀H₂₂O₉**, and the molecular weight of this segment is **286.28 g/mol** (note: the full polymer has a much higher MW due to polymerization).
How should HPMCAS be stored?
Store HPMCAS in a **cool, dry place at ambient temperature**, away from direct sunlight and moisture, in a tightly sealed container.
What grades or types of HPMCAS does Molekula supply?
Molekula supplies **pharmaceutical-grade HPMCAS** (e.g., HPMCAS-LF, HPMCAS-HF) with varying substitution levels for specific dissolution profiles—confirm exact grades and specifications upon inquiry.
Can Molekula supply HPMCAS in bulk quantities?
Yes, Molekula can provide HPMCAS in **bulk quantities** (e.g., 25kg drums, 1MT+), with flexible packaging options—contact us for pricing and lead times tailored to your order size.
What documentation is provided with an HPMCAS order?
Each order includes a **Certificate of Analysis (CoA)**, **Material Safety Data Sheet (MSDS)**, and **batch-specific documentation** (e.g., dissolution profile data for pharmaceutical grades) upon request.
