Chemical Structure

Lercanidipine Impurity N7 CAS 142592-09-4 chemical structure

Description

The occurrence of Lercanidipine Impurity N7 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Lercanidipine Impurity N7 (CAS 142592-09-4), a pharmacopoeial impurity reference standard (molecular formula C17H19NO8, MW 365.34 g/mol) used for the identification and quantification of trace impurities in APIs.

Lercanidipine Impurity N7 (C17H19NO8) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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 Lercanidipine Impurity N7 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.
