4-Methyl-5-(2-phenylethyl)-4h-1,2,4-triazol-3-yl hydrosulfide CAS 663181-83-7

Description

The occurrence of 4-Methyl-5-(2-phenylethyl)-4h-1,2,4-triazol-3-yl hydrosulfide is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Methyl-5-(2-phenylethyl)-4h-1,2,4-triazol-3-yl hydrosulfide (CAS 663181-83-7), molecular formula C11H13N3S and molecular weight 219.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H13N3S, 4-Methyl-5-(2-phenylethyl)-4h-1,2,4-triazol-3-yl hydrosulfide 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 219.31 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
