Crosspovidone, also known as PVPP, is a cross-linked polymer of N-vinyl-2-pyrrolidone. It serves as an effective disintegrant in pharmaceutical formulations. The chemical structure corresponds to the formula (C6H9NO)n with CAS number 25088-87-7. This excipient is compliant with USP and BP standards for purity.
Store in cool, dry conditions below 25°C to prevent moisture absorption. Avoid inhalation of dust; use appropriate respiratory protection during handling. No specific clinical restrictions apply for standard pharmaceutical grades.
