For pharmaceutical manufacturers, the quality and consistency of excipients are non-negotiable. Hypromellose Acetate Succinate (HPMCAS) plays a vital role in advanced drug delivery, and understanding its quality specifications is paramount. NINGBO INNO PHARMCHEM CO.,LTD. provides pharmaceutical grade HPMCAS that adheres to stringent quality controls, ensuring optimal performance in formulations.

Key quality parameters for HPMCAS include its viscosity, which influences film formation and processing. The viscosity of HPMCAS, typically measured in mPa.s for a specific concentration and solvent, is a critical factor for enteric coating applications and in solid dispersion processes. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its pharmaceutical grade Hypromellose Acetate Succinate meets the specified viscosity ranges required for reliable performance.

Another crucial aspect is the degree of substitution of acetyl and succinoyl groups. These chemical modifications determine the pH-dependent solubility of HPMCAS, which is fundamental for its enteric coating functionality. NINGBO INNO PHARMCHEM CO.,LTD. precisely controls these substitution levels to offer grades with distinct pH opening points, allowing formulators to target specific regions of the gastrointestinal tract for drug release. When you buy HPMCAS, verifying these substitution levels is essential for achieving desired results.

Compliance with pharmacopoeial standards is a hallmark of pharmaceutical grade excipients. NINGBO INNO PHARMCHEM CO.,LTD.'s HPMCAS is manufactured to meet the requirements of major pharmacopoeias such as the USP (United States Pharmacopeia) and CP (Chinese Pharmacopoeia). This includes specifications for loss on drying, residue on ignition, and the absence of excessive free acids. These measures ensure the safety and purity of the excipient for use in human medicine.

By maintaining high standards for pharmaceutical grade Hypromellose Acetate Succinate, NINGBO INNO PHARMCHEM CO.,LTD. supports the development of robust and effective drug products. Their commitment to quality ensures that formulators can confidently integrate HPMCAS into their formulations, whether for precise enteric coatings or for enhancing the solubility of poorly soluble APIs. Partnering with NINGBO INNO PHARMCHEM CO.,LTD. guarantees access to excipients that meet the highest pharmaceutical quality benchmarks.
