Mefenamic Acid

Mefenamic Acid Impurities

Mefenamic Acid is a nonsteroidal anti-inflammatory drug (NSAID) of the anthranilic acid (fenamate) class, used in the treatment of pain, inflammation, and dysmenorrhea. Its impurity profile includes structurally related analogs, residual solvents, and degradation products formed under stress conditions such as hydrolysis, oxidation, and photolysis. Furthermore, typical degradation pathways involve oxidative modification of the anthranilic acid core, hydrolytic cleavage of amide bonds, and rearrangement of substituents within the aromatic scaffold. These impurities may affect the drug’s potency, stability, and safety. Importantly, all impurities are structurally characterized and qualified according to ICH guidelines for toxicological assessment and analytical validation.

Mefenamic Acid EP Impurities

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

Mefenamic Acid Related Compounds

Structurally related compounds and synthetic analogs associated with Mefenamic Acid are included for impurity identification, toxicological qualification, and regulatory submission. Consequently, 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.

Mefenamic Acid Impurity Reference Standards

Mefenamic Acid 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. Additionally, EP/USP traceable entries are available upon request and are routinely re-tested to ensure consistency and reliability.
