Beraprost Impurity 27 CAS CATO-C4X-218427

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Beraprost Impurity 27.

CATO supplies Beraprost Impurity 27 (CAS CATO-C4X-218427), a pharmacopoeial impurity reference standard (molecular formula C24H31O5Na, MW 422.50 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Beraprost Impurity 27 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 422.50 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), Beraprost Impurity 27 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.
