Celecoxib Impurity 20 CAS 585-74-0

Description

Compared with other compounds in its class, the molecular weight of 134.18 g/mol gives Celecoxib Impurity 20 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Celecoxib Impurity 20 (CAS 585-74-0), a pharmacopoeial impurity reference standard (molecular formula C9H10O, MW 134.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Celecoxib Impurity 20 (C9H10O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Celecoxib Impurity 20 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.
