Chemical Structure
Description
3-Bromo-5-fluoro-2-methoxyaniline hydrochloride (C7H7BrFNOHCl) contains an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-Bromo-5-fluoro-2-methoxyaniline hydrochloride (CAS 1820747-56-5), molecular formula C7H7BrFNOHCl and molecular weight 256.50 g/mol, is a CATO reference standard with documented purity and traceability.
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.
