CAS 403-29-2 — 4-Fluorophenacyl bromide

4-Fluorophenacyl bromide is an aromatic halide used primarily as a derivatizing agent in analytical chemistry, particularly for the identification of carboxylic acids via GC-MS or HPLC. It reacts selectively to form stable, volatile derivatives, improving separation and detection. This chemical has a CAS number of 403-29-2, a molecular formula of C₈H₆BrFO (not C₅H₅NO₂—likely a typo in your input), and a molecular weight of 215.03 g/mol. It is stored at ambient conditions with no signal word indicating hazard. Molekula supplies 4-fluorophenacyl bromide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
