Chemical Structure
Description
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 supplies Lercanidipine Impurity 64（Z-Isomer） (CAS 119128-13-1), a pharmacopoeial impurity reference standard (molecular formula C12H11NO5, MW 249.22 g/mol) used for the identification and quantification of trace impurities in APIs.
Lercanidipine Impurity 64（Z-Isomer） (C12H11NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Lercanidipine Impurity 64（Z-Isomer） 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.
