5-(5-(Allylthio)-4-methyl-4H-1,2,4-triazol-3-yl)-4-methyl-2-phenylthiazole CAS 338760-18-2

Description

5-(5-(Allylthio)-4-methyl-4H-1,2,4-triazol-3-yl)-4-methyl-2-phenylthiazole (CAS 338760-18-2), molecular formula C16H16N4S2 and molecular weight 328.46 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H16N4S2, 5-(5-(Allylthio)-4-methyl-4H-1,2,4-triazol-3-yl)-4-methyl-2-phenylthiazole 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 328.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
