Chemical Structure

4-Propyl-4h-1,2,4-triazole-3-thiol CAS 27105-99-3 chemical structure

Description

The molecular framework of 4-Propyl-4h-1,2,4-triazole-3-thiol (C5H9N3S) is characterized by a nitrile group, sulfur-containing functionality. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

4-Propyl-4h-1,2,4-triazole-3-thiol (CAS 27105-99-3), molecular formula C5H9N3S and molecular weight 143.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.
