New spectrophotometric method for determination of cephazolin.
A simple, selective and accurate spectrophotometric method has been developed for the determination of the cephalosporin-type antibiotic cephazolin. The method is based on the fast preliminary acid hydrolysis of cephazolin and the spectrophotometric determination of one of its degradation products-2-mercapto-5-methylthiadiazole.
