Chemical Structure
Description
The occurrence of 5-chloro-1-ethyl-2-methyl-4-nitro-1H-imidazole 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-1-ethyl-2-methyl-4-nitro-1H-imidazole (CAS 2302-28-5) is a high-purity analytical reference standard with the molecular formula C6H8ClN3O2 and a molecular weight of 189.60 g/mol.
5-chloro-1-ethyl-2-methyl-4-nitro-1H-imidazole (C6H8ClN3O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
