Description

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.

3-Phenyl-5-(thiophen-2-yl)-4-(p-tolyl)-4H-1,2,4-triazole (CAS 332910-41-5) is a high-purity analytical reference standard with the molecular formula C19H15N3S and a molecular weight of 317.41 g/mol.

Structurally, 3-Phenyl-5-(thiophen-2-yl)-4-(p-tolyl)-4H-1,2,4-triazole (C19H15N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 317.41 g/mol, it falls into the moderately-high-molecular-weight range. 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).
