Entacapone Impurity 24 CAS 4097-63-6 chemical structure

Description

Entacapone Impurity 24 (CAS 4097-63-6) is a certified pharmaceutical impurity reference standard with the molecular formula C7H6N2O6 and a molecular weight of 214.13 g/mol.

Entacapone Impurity 24 (C7H6N2O6) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, 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 Entacapone Impurity 24 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.
