Diclofenac EP Impurity C, chemically defined as [2-[(2,6-Dichlorophenyl)amino]phenyl]methanol and widely recognized as Diclofenac Alcohol or Diclofenac USP Related Compound C, is a benzylic alcohol impurity of Diclofenac, with molecular formula C₁₃H₁₁Cl₂NO and molecular weight 268.14 g/mol. This impurity arises from the oxidative decarboxylation pathway of the acetic acid side chain of the parent NSAID and is redox-related to the corresponding aldehyde (Diclofenac EP Impurity B); both species are typically observed together in oxidative and photolytic stress studies. This makes it a key marker for degradation profiling, stability-indicating method development, and shelf-life evaluation of Diclofenac products. Manufactured at Chemicea under precisely controlled synthetic and analytical protocols, this reference standard supports impurity identification, method validation (AMV), and quality-control testing in accordance with EP, BP, and USP monograph requirements for Diclofenac Sodium and Diclofenac Potassium, and is routinely used in ANDA and DMF regulatory filings. Each batch is supplied with a comprehensive Certificate of Analysis supported by HPLC, ¹H-NMR, and Mass Spectrometry characterization data, ensuring dependable analytical traceability for pharmaceutical R&D and QC laboratories worldwide.
