Belumosudil Impurity 37 CAS CATO-C4X-298837

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Belumosudil Impurity 37.

CATO supplies Belumosudil Impurity 37 (CAS CATO-C4X-298837), a pharmacopoeial impurity reference standard (molecular formula C19H19N3O5, MW 369.37 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Belumosudil Impurity 37 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.37 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 Belumosudil Impurity 37 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.
