3-bromo-5-chloro-1,2,4-thiadiazole CAS 37159-60-7

Description

Compared with other compounds in its class, the molecular weight of 203.49 g/mol gives 3-bromo-5-chloro-1,2,4-thiadiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-bromo-5-chloro-1,2,4-thiadiazole (CAS 37159-60-7), a certified reference material (molecular formula C2H4BrClN2S, MW 203.49 g/mol) for analytical method development and quality control.

3-bromo-5-chloro-1,2,4-thiadiazole (C2H4BrClN2S) contains sulfur-containing functionality, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
