Chemical Structure
Description
The occurrence of 3-Bromo-2,5-difluoroaniline hydrochloride is closely related to a nitrile group, fluorine/chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Bromo-2,5-difluoroaniline hydrochloride (CAS 1787929-07-0), a certified reference material (molecular formula C6H4BrF2NHCl, MW 244.46 g/mol) for analytical method development and quality control.
3-Bromo-2,5-difluoroaniline hydrochloride (C6H4BrF2NHCl) contains a nitrile group, fluorine/chlorine/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.
