((1,2,4-Thiadiazol-5-yl)amino)methanol CAS 1190921-45-9

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 ((1,2,4-Thiadiazol-5-yl)amino)methanol (CAS 1190921-45-9), a certified reference material (molecular formula C3H5N3OS, MW 131.16 g/mol) for analytical method development and quality control.

The molecular framework of ((1,2,4-Thiadiazol-5-yl)amino)methanol (C3H5N3OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
