Chemical Structure

Bevantolol Impurity 12 CAS 747351-40-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bevantolol Impurity 12.

As a process- or degradation-related impurity, Bevantolol Impurity 12 (CAS 747351-40-2, C20H27NO4) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Bevantolol Impurity 12 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 345.43 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), Bevantolol Impurity 12 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.
