Chemical Structure

Enalapril Impurity 7 CAS CATO-C4X-13347 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 204.22 g/mol gives Enalapril Impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Enalapril Impurity 7 (CAS CATO-C4X-13347), a pharmacopoeial impurity reference standard (molecular formula C12H12O3, MW 204.22 g/mol) used for the identification and quantification of trace impurities in APIs.

Enalapril Impurity 7 (C12H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 Enalapril Impurity 7 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.
