USP Methods for the Analysis of Procainamide

  Application Notes: Procainamide is a common antiarrhythmic agent used to treat cardiac arrhythmias. According to USP methods procainamide hydrochloride contains not less than 98% and no more than 102% procainamide based on the dried basis. The USP HPLC method for the separation of procainamide and 4-aminobenzoic was developed on Legacy L1 column according to the US Pharmacopeia methodology. L1 classification is assigned to reversed-phase HPLC column containing C18 ligand. Support for the material is spherical silica gel with particles size 3-10 um and pore size of 100-120A. Resolution between critical pairs corresponds to rules and specifications of UPS. Reference: USP 35- NF30
