4-Allyl-5-[(2-amino-1,3-thiazol-4-yl)methyl]-2,4-dihydro-3H-1,2,4-triazole-3-thione (CAS 690643-10-8), molecular formula C9H11N5S2 and molecular weight 253.35 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H11N5S2, 4-Allyl-5-[(2-amino-1,3-thiazol-4-yl)methyl]-2,4-dihydro-3H-1,2,4-triazole-3-thione contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.35 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
