CATO supplies Imatinib Impurity 69 (CAS 404577-34-0), a pharmacopoeial impurity reference standard (molecular formula C11H21NO5S, MW 279.35 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, Imatinib Impurity 69 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Imatinib 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.
