Chemical Structure

4-(2-Propen-1-yl)-5-thioxo-1,2,4-triazolidin-3-one CAS 136794-22-4 chemical structure

Description

The molecular framework of 4-(2-Propen-1-yl)-5-thioxo-1,2,4-triazolidin-3-one (C5H7N3OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

4-(2-Propen-1-yl)-5-thioxo-1,2,4-triazolidin-3-one (CAS 136794-22-4) is a high-purity analytical reference standard with the molecular formula C5H7N3OS and a molecular weight of 157.19 g/mol.

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.
