Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Nimodipine Impurity 44 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 307.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies Nimodipine Impurity 44 (CAS CATO-C4X-138544), a pharmacopoeial impurity reference standard (molecular formula C15H17NO6, MW 307.30 g/mol) used for the identification and quantification of trace impurities in APIs.
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 Nimodipine Impurity 44 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.
