Residual solvents in pharmaceuticals are defined as volatile organic compounds used in or generated from the manufacture of drug 1:Hexane
substances, pharmaceutical additives, or drug products. They are strictly controlled according to risk classifications from Class 1 to Class 3, 2:Nitromethane
which are based on the risk to human health. 3:Chloroform
Headspace GC methods specified in the USP (U.S. Pharmacopeia), General Chapters <467> Residual Solvents, are commonly used for 4:1,2-Dimethoxyethane
analysis of residual solvents.Presented here is an analysis of residual solvents as described in USP<467> carried out with an HS-20 5:Trichloroethene
6:Pyridine
headspace sampler and a Shimadzu Nexis GC-2030 Gas Chromatograph. 3 7:Methylbutylketone
8:Tetraline
