2-Amino-4-(3,4-difluorophenyl)thiazole-5-carbonitrile (CAS 1139743-02-4), molecular formula C10H5F2N3S and molecular weight 237.23 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H5F2N3S, 2-Amino-4-(3,4-difluorophenyl)thiazole-5-carbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 237.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
