Chemical Structure
Description
As a certified reference material (CRM), Betaxolol Impurity 14 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.
CATO supplies Betaxolol Impurity 14 (CAS CATO-C4X-155914), a pharmacopoeial impurity reference standard (molecular formula C19H22O2, MW 282.38 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, a hydroxyl group, an ether linkage, Betaxolol Impurity 14 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 282.38 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.
