Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Chloro-3-(2,2,2-trifluoroethyl)-1,2,4-thiadiazole (CAS 1484792-54-2), a certified reference material (molecular formula C4H2ClF3N2S, MW 202.59 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, 5-Chloro-3-(2,2,2-trifluoroethyl)-1,2,4-thiadiazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.59 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.
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.
