Chemical Structure

Triamcinolone Acetonide Impurity 49 CAS 7704-77-0 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 Triamcinolone Acetonide Impurity 49.

CATO supplies Triamcinolone Acetonide Impurity 49 (CAS 7704-77-0), a pharmacopoeial impurity reference standard (molecular formula C25H33FO6, MW 448.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Triamcinolone Acetonide Impurity 49 (C25H33FO6) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 Triamcinolone Acetonide Impurity 49 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.
