Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, 3,5-Dibromo-1-(methoxymethyl)-1H-1,2,4-triazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.91 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.
CATO supplies 3,5-Dibromo-1-(methoxymethyl)-1H-1,2,4-triazole (CAS 1785762-67-5), a certified reference material (molecular formula C4H5Br2N3O, MW 270.91 g/mol) for analytical method development and quality control.
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.
