Chemical Structure
Description
The occurrence of 2-Chloro-4-iodo-5-nitrobenzoic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Chloro-4-iodo-5-nitrobenzoic acid (CAS 855471-35-1) is a high-purity analytical reference standard with the molecular formula C7H3ClINO4 and a molecular weight of 327.46 g/mol.
2-Chloro-4-iodo-5-nitrobenzoic acid (C7H3ClINO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
