Chemical Structure
Description
The occurrence of 2,5-Dibromo-4-fluoro-1-methyl-1H-imidazole is closely related to a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,5-Dibromo-4-fluoro-1-methyl-1H-imidazole (CAS 1824064-07-4), a certified reference material (molecular formula C4H3Br2FN2, MW 257.89 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine/bromine substitution, 2,5-Dibromo-4-fluoro-1-methyl-1H-imidazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.89 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.
