4-Ethyl-5-(1-(p-tolyloxy)ethyl)-4H-1,2,4-triazole-3-thiol CAS 669705-05-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-Ethyl-5-(1-(p-tolyloxy)ethyl)-4H-1,2,4-triazole-3-thiol (CAS 669705-05-9) is a high-purity analytical reference standard with the molecular formula C13H17N3OS and a molecular weight of 263.36 g/mol.

The molecular framework of 4-Ethyl-5-(1-(p-tolyloxy)ethyl)-4H-1,2,4-triazole-3-thiol (C13H17N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

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.
