Chemical Structure

Belumosudil Impurity 24 CAS 23705-43-3 chemical structure

Description

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Belumosudil Impurity 24 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a process- or degradation-related impurity, Belumosudil Impurity 24 (CAS 23705-43-3, C3H9NO3S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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 24 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.
