Chemical Structure

N1-(5-methyl-1,3,4-thiadiazol-2-yl)ethane-1,2-diamine CAS 933690-81-4 chemical structure

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 N1-(5-methyl-1,3,4-thiadiazol-2-yl)ethane-1,2-diamine (CAS 933690-81-4), a certified reference material (molecular formula C5H10N4S, MW 158.22 g/mol) for analytical method development and quality control.

N1-(5-methyl-1,3,4-thiadiazol-2-yl)ethane-1,2-diamine (C5H10N4S) contains a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
