The study acylation reactions of dihydroquercetin apart from scientific interest has practical value. As a result of the reactions will form new organic compounds which may possess potential antioxidant, anti-inflammatory and cytotoxic activity [1]. Within this research studying of processes of acylation of a dihydroquercetin with use of benzoyl chloride and definition of chemical structure of new medicinal substances, as homogeneous samples of high degree of purity was the important and interesting point. One of the promising methods of studying the structure of drug substances is the method of IR spectroscopy. The method gives the chance to make an objective assessment of authenticity that allows to use actively it in the pharmaceutical analysis of many unknown connections [2-4]. It predetermined conduct of the compulsory registration of IR spectra for the original dihydroquercetin and synthesized on its basis of new substances with benzoyl chloride.
