3-(4-Amino-5-mercapto-4h-1,2,4-triazol-3-yl)propan-1-ol CAS 828295-64-3

Description

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-(4-Amino-5-mercapto-4h-1,2,4-triazol-3-yl)propan-1-ol is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.22 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 3-(4-Amino-5-mercapto-4h-1,2,4-triazol-3-yl)propan-1-ol (CAS 828295-64-3), a certified reference material (molecular formula C5H10N4OS, MW 174.22 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.
