Levamisole: its stability in aqueous solutions at elevated temperatures. Part I. Isolation and identification of decomposition products formed in aqueous solutions of levamisole stored under nitrogen and oxygen at 100 °C

Abstract

Solutions of l-tetramisole (levamisole) buffered over a pH range of 2 to 8 were stored under nitrogen and oxygen at 100 °C. The decomposition that occurred was detected by thin-layer chromatography. The decomposition products were isolated and their structures elucidated by standard instrumental procedures.
