Chemical Structure
Description
The occurrence of 6-bromo-4-fluoro-1,2-dimethyl-benzimidazole 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 6-bromo-4-fluoro-1,2-dimethyl-benzimidazole (CAS 2189739-26-0), a certified reference material (molecular formula C9H16BrFN2, MW 251.14 g/mol) for analytical method development and quality control.
6-bromo-4-fluoro-1,2-dimethyl-benzimidazole (C9H16BrFN2) contains a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
