Chemical Structure
Description
The occurrence of 5-Chloro-3-nitro-1H-pyrrolo[2,3-c]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.
5-Chloro-3-nitro-1H-pyrrolo[2,3-c]pyridine (CAS 1167056-19-0) is a high-purity analytical reference standard with the molecular formula C7H4ClN3O2 and a molecular weight of 197.58 g/mol.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 5-Chloro-3-nitro-1H-pyrrolo[2,3-c]pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
