Chemical Structure
Description
The occurrence of 3,4-Dibromo-2-fluorobenzoyl chloride is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,4-Dibromo-2-fluorobenzoyl chloride (CAS 1803716-16-6), molecular formula C7H2Br2ClFO and molecular weight 316.35 g/mol, is a CATO reference standard with documented purity and traceability.
3,4-Dibromo-2-fluorobenzoyl chloride (C7H2Br2ClFO) contains a hydroxyl group, an ether linkage, 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.
