Description
CATO supplies Pyridoxine impurity 69 (CAS CATO-C4X-187769), a pharmacopoeial impurity reference standard (molecular formula C16H20N2O5HCl, MW 356.80 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C16H20N2O5HCl, Pyridoxine impurity 69 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 356.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Pyridoxine impurity 69 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
