4-Allyl-5-(2-ethoxyphenyl)-4H-1,2,4-triazole-3-thiol CAS 725705-51-1

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-Allyl-5-(2-ethoxyphenyl)-4H-1,2,4-triazole-3-thiol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 261.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 4-Allyl-5-(2-ethoxyphenyl)-4H-1,2,4-triazole-3-thiol (CAS 725705-51-1), a certified reference material (molecular formula C13H15N3OS, MW 261.34 g/mol) for analytical method development and quality control.

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.

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.
