Pinaverium impurity 34 CAS 1970218-63-3

Description

The occurrence of Pinaverium impurity 34 is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Pinaverium impurity 34 (CAS 1970218-63-3) is a certified pharmaceutical impurity reference standard with the molecular formula C17H31NO2 and a molecular weight of 281.43 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Pinaverium impurity 34 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.43 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.

As a certified reference material (CRM), Pinaverium impurity 34 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
