Chemical Structure

Indometacin Impurity 40 CAS CATO-C4X-147040 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Indometacin Impurity 40.

CATO supplies Indometacin Impurity 40 (CAS CATO-C4X-147040), a pharmacopoeial impurity reference standard (molecular formula C37H48ClNO6, MW 638.23 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Indometacin Impurity 40 (C37H48ClNO6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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 Indometacin Impurity 40 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.
