Cefixime EP Impurity A (Mixture of Diastereomers) usage and description
Cefixime EP Impurity A (Mixture of Diastereomers) is a mixture of two or more stereoisomers of Cefixime, which is a third-generation cephalosporin antibiotic used for the treatment of various bacterial infections. The impurity A mixture is commonly used as a reference standard for the identification and quantification of impurities in cefixime formulations.
The chemical information of Cefixime EP Impurity A (Mixture of Diastereomers) includes its molecular formula, molecular weight, and chemical structure. The molecular formula of the impurity A mixture is not disclosed, but its molecular weight is approximately 667.76 g/mol. The chemical structure of the impurity A mixture is also not disclosed, but it is likely to be similar to that of cefixime, which contains a beta-lactam ring and a thiazolidine ring.
The usage of Cefixime EP Impurity A (Mixture of Diastereomers) is primarily in the pharmaceutical industry, where it is used as a reference standard for quality control purposes. It is used to determine the purity and identity of cefixime in drug formulations and to monitor the presence of impurities that may affect the safety and efficacy of the drug. The impurity A mixture is also used in research and development of new cefixime formulations and in the development of new analytical methods for the detection and quantification of cefixime impurities.
