Chemical Structure
Description
The occurrence of 5-Chloro-3-fluoro-2-vinylpyridine is closely related to a nitrile group, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Chloro-3-fluoro-2-vinylpyridine (CAS 1374652-70-6) is a high-purity analytical reference standard with the molecular formula C7H5ClFN and a molecular weight of 157.57 g/mol.
5-Chloro-3-fluoro-2-vinylpyridine (C7H5ClFN) contains a nitrile group, fluorine/chlorine 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).
