Selected wavelength of maximum absorption λ max . for a solution of tinidazole in phosphate buffer (pH = 6.86) is 317.3 nm. The calibration graph shows linearity at the selected wavelength and obeys the Lambert-Bouguer-Beer law in the concentration range of 3.0-30 μg / ml with a correlation coefficient of at least 0.992. Studies have been conducted on the extraction of tinidazole in pharmaceuticals, which is 97.9 - 100.4%, which confirms the accuracy of the proposed method. The metrological evaluation of the developed spectrophotometric method showed good reproducibility and accuracy of the determination of tinidazole in mono- and multicomponent pharmaceutical products from various manu-facturers. The relative error in the determination of tinidazole does not exceed 2%. Statistical processing of the data obtained shows that the proposed method can be successfully applied for routine analysis of the stability of tinidazole in laboratories for quality control of drugs.","PeriodicalId":23473,"journal":{"name":"Universum:Chemistry & biology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87561825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
