CAS No: 9003-39-8
Molecular Formula: (C6H9NO)n
 

PVP (Pharmaceutical grade) is a kind of new excellent pharmaceutical excipient. It is mainly used as binder for tablet and granule, dissolving assistant for injection, flow assistant for capsule, dispersant for liquid medicine and pigment, stabilizer for enzyme and heat-sensitive drug, coprecipitant for poorly soluble drugs, lubricator and antitoxic assistant for eye drug. PVP has been used as excipient in more than one hundred drugs.
Physical properties:
PVP exists in white powder or aqueous solution. PVP readily dissolves in water, alcohol, amine and halohydrocarbon, but is not dissolved in and aether etc.. It has good solubility, biocompatibility, and physiologically inert, film-forming character, colloid protect ability and compound ability to many organic or inorganic compounds.
