Elaboration of Techniques for Quality Control of a New Active Pharmaceutical Substance of 3-(1h-benzimidazol-2-yl) -1,2,2-trimethyl cyclopentancarbonic acid

Abstract

The article presents the results of the elaboration of techniques for identification and assay of a new active pharmaceutical substance (API) – 3- (1H-benzimidazol-2-yl) -1,2,2-trimethylcyclopentane-carboxylic acid. To identify the API, the method of IR spectroscopy was used, the assay was carried out using the method of direct acidimetric titration in a medium of glacial acetic acid. Methods were validated in accordance with the requirements of the State Pharmacopoeia of the Russian Federation and are suitable for further use in quality control in the production of 3- (1H-benzimidazol-2-yl) -1,2,2-trimethylcyclopentane-carboxylic acid.
