CAS 459-46-1 — 4-Fluorobenzyl bromide

4-Fluorobenzyl bromide is an aromatic organobromine compound featuring a fluorine substituent at the para position, widely used as an intermediate in pharmaceutical synthesis, agrochemical production, and materials science for introducing fluorinated benzyl groups into target molecules. It is a clear to pale yellow liquid with a pungent odor, soluble in organic solvents but insoluble in water. CAS 459-46-1, molecular formula C7H6BrF, molecular weight 189.04 g/mol, boiling point 102–104°C at 12 mmHg, density ~1.45 g/cm³. Non-classified under GHS (no signal word), but handle under fume hood due to volatility and potential skin/eye irritation. Purity typically ≥97% for research and industrial applications. Molekula supplies 4-fluorobenzyl bromide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
