Fudosteine Impurity 26 CAS 50727-79-2 chemical structure

Description

CATO manufactures Fudosteine Impurity 26 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.

CATO supplies Fudosteine Impurity 26 (CAS 50727-79-2), a pharmacopoeial impurity reference standard (molecular formula C9H18N2O4S2, MW 282.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Fudosteine Impurity 26 (C9H18N2O4S2) contains an amide group, a sulfone group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
