Chemical Structure
Description
The occurrence of 6-Chloro-3-nitro-1H-pyrrolo[3,2-b]pyridine 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.
6-Chloro-3-nitro-1H-pyrrolo[3,2-b]pyridine (CAS 1190311-54-6) is a high-purity analytical reference standard with the molecular formula C7H4ClN3O2 and a molecular weight of 197.58 g/mol.
6-Chloro-3-nitro-1H-pyrrolo[3,2-b]pyridine (C7H4ClN3O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
