Chemical Structure
Description
The occurrence of 4-Acetyl-2,5-difluorobenzonitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Acetyl-2,5-difluorobenzonitrile (CAS 198280-43-2) is a high-purity analytical reference standard with the molecular formula C9H5F2NO and a molecular weight of 181.14 g/mol.
4-Acetyl-2,5-difluorobenzonitrile (C9H5F2NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
