Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pinaverium Chloride Impurity 18.
Pinaverium Chloride Impurity 18 (CAS CATO-C4X-246718) is a certified pharmaceutical impurity reference standard with the molecular formula C26H41BrNO4Cl and a molecular weight of 546.97 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, Pinaverium Chloride Impurity 18 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 546.97 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).
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 Chloride Impurity 18 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.
