Chemical Structure
Description
The occurrence of 2-Bromo-1-ethynyl-3-fluorobenzene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-1-ethynyl-3-fluorobenzene (CAS 1855543-30-4) is a high-purity analytical reference standard with the molecular formula C8H4BrF and a molecular weight of 199.02 g/mol.
2-Bromo-1-ethynyl-3-fluorobenzene (C8H4BrF) contains fluorine/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).
