Description
CATO supplies Salicylic Acid Impurity 35 (CAS CATO-C4X-190235), a pharmacopoeial impurity reference standard (molecular formula C8H8O6S, MW 232.21 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Salicylic Acid Impurity 35 (C8H8O6S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Salicylic Acid Impurity 35 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.
