4-(2-Ethylphenyl)-5-methyl-4H-1,2,4-triazole-3-thiol CAS 669755-34-4

Description

The occurrence of 4-(2-Ethylphenyl)-5-methyl-4H-1,2,4-triazole-3-thiol 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-(2-Ethylphenyl)-5-methyl-4H-1,2,4-triazole-3-thiol (CAS 669755-34-4), 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-(2-Ethylphenyl)-5-methyl-4H-1,2,4-triazole-3-thiol 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 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).
