CATO supplies 5-((3-Bromobenzyl)thio)-4-cyclopropyl-2,4-dihydro-3h-1,2,4-triazol-3-one (CAS 923231-89-4), a certified reference material (molecular formula C12H12BrN3OS, MW 326.21 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, 5-((3-Bromobenzyl)thio)-4-cyclopropyl-2,4-dihydro-3h-1,2,4-triazol-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
