Description
CATO manufactures Celecoxib Impurity 68 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, Celecoxib Impurity 68 (CAS 170569-91-2, C17H14F3N3O3S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Celecoxib Impurity 68 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.37 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.
