Cloxacillin

Cloxacillin Impurities

Cloxacillin is a semi-synthetic penicillin antibiotic used to treat infections caused by penicillinase-producing staphylococci. Its impurity profile includes structurally related analogs, residual solvents, and degradation products formed under stress conditions such as hydrolysis, oxidation, and photolysis. Degradation pathways typically involve hydrolytic cleavage of the beta-lactam ring, oxidation of the isoxazolyl side chain, and rearrangement of the carboxyl group. These impurities may affect the drug’s potency, stability, and safety. All impurities are structurally characterized and qualified in accordance with ICH guidelines for toxicological assessment and analytical validation.

Cloxacillin EP Impurities

Pharmacopeial and non-pharmacopeial Cloxacillin impurity compounds are available in compliance with European Pharmacopoeia (EP) specifications. These standards support analytical method development, impurity profiling, and long-term stability studies. EP traceable materials are supplied with validated analytical data, including purity, structural confirmation, and spectral characterization.

Cloxacillin Related Compounds

Structurally related compounds and synthetic analogs associated with Cloxacillin are included for use in impurity identification, toxicological qualification, and regulatory submission. These related substances are used in forced degradation studies, genotoxicity assessments, and impurity threshold evaluations. They are essential for understanding the impurity profile and ensuring compliance with regulatory limits.

Cloxacillin Impurity Reference Standards

Cloxacillin impurity reference standards are provided with validated analytical data, including purity, NMR, MS, and full Certificates of Analysis. These standards are used in pharmaceutical research, method validation, and GMP-compliant quality control. EP/USP traceable entries are available upon request and are routinely re-tested to ensure consistency and reliability.
