1-(2-Ethoxyphenyl)-1H-1,2,3,4-tetrazole-5-thiol CAS 22347-26-8

Description

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.

CATO supplies 1-(2-Ethoxyphenyl)-1H-1,2,3,4-tetrazole-5-thiol (CAS 22347-26-8), a certified reference material (molecular formula C9H10N4OS, MW 222.27 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 1-(2-Ethoxyphenyl)-1H-1,2,3,4-tetrazole-5-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
