3-bromo-5-methyl-1,2,4-thiadiazole CAS 522647-42-3

Description

Compared with other compounds in its class, the molecular weight of 183.07 g/mol gives 3-bromo-5-methyl-1,2,4-thiadiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-bromo-5-methyl-1,2,4-thiadiazole (CAS 522647-42-3), a certified reference material (molecular formula C3H7BrN2S, MW 183.07 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, bromine substitution, 3-bromo-5-methyl-1,2,4-thiadiazole is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
