Chemical Structure
Description
CATO supplies 5-Bromo-1,2-dichloro-3-(trifluoromethyl)benzene (CAS 392-89-2), a certified reference material (molecular formula C7H2BrCl2F3, MW 293.90 g/mol) for analytical method development and quality control.
5-Bromo-1,2-dichloro-3-(trifluoromethyl)benzene (C7H2BrCl2F3) contains fluorine/chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
