Chemical Structure
Description
CATO supplies Fudosteine Impurity 9 (CAS CATO-C4X-14479), a pharmacopoeial impurity reference standard (molecular formula C9H18ClNO3SHCl, MW 292.21 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Fudosteine Impurity 9 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 292.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Fudosteine Impurity 9 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.
