Chemical Structure

Dotinurad Impurity 41 CAS CATO-C4X-249441 chemical structure

Description

Structurally, Dotinurad Impurity 41 (C14H16N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 276.42 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies Dotinurad Impurity 41 (CAS CATO-C4X-249441), a pharmacopoeial impurity reference standard (molecular formula C14H16N2S2, MW 276.42 g/mol) used for the identification and quantification of trace impurities in APIs.

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.
