Chemical Structure
Description
The occurrence of 3-Fluorobenzalbromide is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Fluorobenzalbromide (CAS 455-34-5) is a high-purity analytical reference standard with the molecular formula C7H5Br2F and a molecular weight of 267.92 g/mol.
Based on its molecular formula C7H5Br2F, 3-Fluorobenzalbromide contains fluorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
