The LC-QTOF-MS/MS analysis of acid degradation products of Rifaximin, An Antibiotic
Description
The present research aims to propose a simple and accurate technique for the analysis of Rifaximin in the presence of its stress degradation products and analysis of degradation products by LC-MS/MS analysis. Rifaximin was submitted to forced degradation under acid hydrolysis condition as prescribed by the ICH.The active Rifaximin was complementary provided by Hilton Pharma Pvt Ltd, and the extract was prepared by firstly treated with HCl and heated about 4 to 8 hours. The filtrate was collected and separated using dichloromethane followed by evaporation in rotary evaporator to obtain a solid crude extract which was then stored under refrigeration at - 80 0 C. Liquid chromatography quadrupole time of flight mass spectrometry (LC- QTOF-MS/MS) was utilized to identify products in the drug sample. The data processing results revealed the presence of 9 products in the degraded sample of Rifaximin. This data article contains the m/z [M+H + ] values, molecular formula, retention times and the comprehensive list of m/z values detected during the LC- QTOF- MS/MS analysis.
