Chemical Structure

4-Fluoro-2-nitrobenzoyl chloride CAS 57750-82-0 chemical structure

Description

4-Fluoro-2-nitrobenzoyl chloride (C7H3ClFNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
