The purpose of the study: Creating scientific approaches to the chromatography with mass spectrometry methods for establishing purity, molecular mass, structure, identification and quantification of a number of derivatives 1,2,4-triazole, development and validation of methods that allow control the content of these substances in intermediates, active pharmaceutical ingredients, drugs and biological liquids. Research methods: High performance liquid chromatography with diode-matrix detection, mass spectrometry, thermodynamic method, pharmacokinetic method. Results and their novelty. The main trends in creating new methods of analysis of 1,2,4-triazole derivatives are to increase the use of HPLC and HPLC-MS methods. However, for the studied derivatives 3-thio-1,2,4-triazoles lag behind the world trends, namely for these substances are usually offered mostly spectrophotometric or potentiometric methods that are insensitive, non-selective.
