Chemical Structure

Arotinolol Impurity 10 CAS CATO-C4X-185410 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 242.34 g/mol gives Arotinolol Impurity 10 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Arotinolol Impurity 10 (CAS CATO-C4X-185410), a pharmacopoeial impurity reference standard (molecular formula C8H6N2OS3, MW 242.34 g/mol) used for the identification and quantification of trace impurities in APIs.

Arotinolol Impurity 10 (C8H6N2OS3) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
