Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Verapamil Impurity 38 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 440.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Verapamil Impurity 38 (CAS 114847-42-6) is a certified pharmaceutical impurity reference standard with the molecular formula C26H36N2O4 and a molecular weight of 440.58 g/mol.
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 Verapamil Impurity 38 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.
