Celecoxib Impurity 37 CAS 326-06-7

Description

Compared with other compounds in its class, the molecular weight of 216.16 g/mol gives Celecoxib Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Celecoxib Impurity 37 (CAS 326-06-7), a pharmacopoeial impurity reference standard (molecular formula C10H7F3O2, MW 216.16 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Celecoxib Impurity 37 (C10H7F3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 37 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.
