Chemical Structure
Description
CATO supplies 5-Chloro-4-((4-iodo-1H-pyrazol-1-yl)methyl)-1,2,3-thiadiazole (CAS 1339700-79-6), a certified reference material (molecular formula C6H4ClIN4S, MW 326.55 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, chlorine/iodine substitution, an aromatic ring system, 5-Chloro-4-((4-iodo-1H-pyrazol-1-yl)methyl)-1,2,3-thiadiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
