Molecular Structural Studies of Captopril Drug, Using Thermal Analysis, Mass Spectral Fragmentation and Semi-Empirical MO- Calculations

Abstract

In this work captopril an antihypertensive (KPL) drug, was investigated using thermal analysis (TA) measurements (TG-DTA) in comparison with electron impact (EI) mass spectral (MS) fragmentation at 70 eV. Semi-empirical molecular (MO) calculations, using PM3 method in the neutral and positively charged forms of the drug. These include molecular geometry… (More)
