Quantification and Validation of Mesylate Ion in Dabigatran Etexilate Mesylate and Simultaneous Separation of Some Pharmaceutical Counterions using HPLC-HILIC Coupled with Corona Charged Aerosol Detector
Abstract
Abstract Several counterions are commonly observed to be associated with drugs to improve their physicochemical properties. Counterions belonging to both inorganic and organic nature, like, I−, NO −, Br−, Cl−, K+, Na+, Li+, PO3− 4, SO2− 4, Zn2+, Mg2+, Ca2+, glutarate, succinate, mesylate, fumarate, citrate, oxalate and tartrate were chosen for the study. HPLC equipped with ZIC®-HILIC column with gradient elution and Corona – CAD was used to...
