Nimesulide

Nimesulide Impurities

Nimesulide impurities include synthetic intermediates, process-related compounds, degradation products, and residual solvents that may arise during synthesis, formulation, or storage. As a selective COX-2 inhibitor used for its anti-inflammatory, analgesic, and antipyretic properties, impurity profiling is essential to ensure product safety, therapeutic efficacy, and regulatory compliance. Known degradation pathways include hydrolysis, oxidative breakdown, and photolytic transformation under stress conditions. All impurity compounds are structurally characterized and qualified under ICH guidelines for toxicological evaluation and analytical validation.

Nimesulide EP Impurities

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

Nimesulide Related Compounds

Structurally related compounds and synthetic analogs associated with Nimesulide are included for use in impurity identification, toxicological qualification, and regulatory submission. These materials are thoroughly characterized and conform to international standards. Related compounds are used in forced degradation studies, genotoxicity assessments, and impurity threshold evaluations.

Nimesulide Impurity Reference Standards

Nimesulide 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.
