Residual solvent analysis in hydrochloride salts of active pharmaceutical ingredients.
GMP conditions commands to control adequately the quality of APIs by checking the levels of residual solvents. Organic solvents such as acetone, ethyl acetate, isopropyl alcohol, methanol, tetrahydrofuran and toluene frequently used in pharmaceutical industry for the manufacturing of Active Pharmaceutical ingredients (APIs). A selective Gas Chromatographic (GC) method has been developed and validated as per ICH guidelines for residual solvent analysis in 10 different hydro chloride salts of APIs. Residual solvents in APIs were monitored using gas chromatography (GC) with Flame Ionisation detector (FID). The separation was carried out on BP 624 column (30 mx0.53 mm i.d.x0.25 m coating thickness), using GC 17 A shimadzu, with nitrogen as carrier gas in the split mode by direct injection method. The method described is simple, sensitive, rugged, reliable and reproducible for the quantitation of acetone, ethyl acetate, isopropyl alcohol, methanol, tetrahydrofuran and toluene at residual level from hydrochloride chloride salts of APIs.
