Chemical Structure
Description
CATO manufactures Imatinib Impurity 61 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.
As a process- or degradation-related impurity, Imatinib Impurity 61 (CAS 62-50-0, C3H8O3S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Imatinib Impurity 61 (C3H8O3S) contains 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.
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.
