Chemical Structure
Description
The occurrence of Pinaverium Impurity 4 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Pinaverium Impurity 4 (CAS CATO-C4X-24674), a pharmacopoeial impurity reference standard (molecular formula C26H41BrNO4Br, MW 591.42 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Pinaverium Impurity 4 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 591.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Pinaverium Impurity 4 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.
