Chemical Structure

2-Chloro-6-nitrobenzoic acid CAS 5344-49-0 chemical structure

Description

The occurrence of 2-Chloro-6-nitrobenzoic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Chloro-6-nitrobenzoic acid (CAS 5344-49-0), molecular formula C7H4ClNO4 and molecular weight 201.56 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H4ClNO4, 2-Chloro-6-nitrobenzoic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 201.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
