4-(Tetrahydrofuran-2-ylmethyl)-5-thien-2-yl-4H-1,2,4-triazole-3-thiol CAS 438030-51-4

Description

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.

CATO supplies 4-(Tetrahydrofuran-2-ylmethyl)-5-thien-2-yl-4H-1,2,4-triazole-3-thiol (CAS 438030-51-4), a certified reference material (molecular formula C11H13N3OS2, MW 267.37 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H13N3OS2, 4-(Tetrahydrofuran-2-ylmethyl)-5-thien-2-yl-4H-1,2,4-triazole-3-thiol contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
