Chemical Structure
Description
The occurrence of 5-Ethyl-4-isopropyl-4h-1,2,4-triazole-3-thiol is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Ethyl-4-isopropyl-4h-1,2,4-triazole-3-thiol (CAS 869941-86-6), a certified reference material (molecular formula C7H13N3S, MW 171.26 g/mol) for analytical method development and quality control.
The molecular framework of 5-Ethyl-4-isopropyl-4h-1,2,4-triazole-3-thiol (C7H13N3S) 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. 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).
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.
