Chemical Structure

2-Ethyl-5-isopropyl-1,3,4-thiadiazole CAS 41398-03-2 chemical structure

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.

2-Ethyl-5-isopropyl-1,3,4-thiadiazole (CAS 41398-03-2) is a high-purity analytical reference standard with the molecular formula C7H12N2S and a molecular weight of 156.25 g/mol.

The molecular framework of 2-Ethyl-5-isopropyl-1,3,4-thiadiazole (C7H12N2S) is characterized by a nitrile group, sulfur-containing functionality. 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.
