Abstract

The data concerning substantiation and development of the methods of quality control for a new biologically active substance with the anticonvulsant action are presented in the article. Identification of the substance under research has been performed by physical and chemical methods (IR-, UV- and PMR-spectroscopy) and by chemical reactions. For quantitative determination of dimetpyrazine the method of acid-base titration in the non-aqueous medium has been developed. The relative uncertainty of the average is 0.51%.
