Chemical Structure
Description
The occurrence of 4-Bromo-3-fluorophenol is closely related to a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-3-fluorophenol (CAS 121219-03-2), molecular formula C6H4BrFO and molecular weight 191.00 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-3-fluorophenol (C6H4BrFO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 191.00 g/mol, it falls into the medium-molecular-weight range. 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.
