Chemical Structure

Thiamazole impurity 9 CAS CATO-C4X-20609 chemical structure

Description

As a process- or degradation-related impurity, Thiamazole impurity 9 (CAS CATO-C4X-20609, C12H14N6S3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Thiamazole impurity 9 (C12H14N6S3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
