HPMCP (Hydroxypropyl Methylcellulose Phthalate) is a synthetic polymer widely used as an enteric coating agent in pharmaceutical manufacturing. Synthesized via esterification of hydroxypropyl methylcellulose with phthalic anhydride, it features the molecular formula C12H14O5(C6H4(COO)n)m and CAS number 9004-88-8.
Storage requires dry conditions below 25°C to prevent hydrolysis. Handling necessitates dust masks to avoid respiratory irritation. Not recommended for patients with known hypersensitivity to cellulose derivatives or phthalates.
