The occurrence of Dexpanthenol Impurity 29 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Dexpanthenol Impurity 29 (CAS 1112-33-0(Free acid), a pharmacopoeial impurity reference standard (molecular formula C6H11O4Ca, MW 187.23 g/mol) used for the identification and quantification of trace impurities in APIs.
Dexpanthenol Impurity 29 (C6H11O4Ca) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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 Dexpanthenol Impurity 29 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.
