Chemical Structure
Description
The occurrence of 2,4-Dichloro-3-fluoronitrobenzene is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4-Dichloro-3-fluoronitrobenzene (CAS 393-79-3) is a high-purity analytical reference standard with the molecular formula C6H2Cl2FNO2 and a molecular weight of 209.99 g/mol.
2,4-Dichloro-3-fluoronitrobenzene (C6H2Cl2FNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
