Chemical Structure
Description
As a process- or degradation-related impurity, Etrasimod Impurity 76 (CAS CATO-C4X-321476, C13H14ClF3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Based on its molecular formula C13H14ClF3, Etrasimod Impurity 76 contains fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 262.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
