Chemical Structure
Description
The occurrence of 2-(4-Fluorophenyl)-4-methyl-5-nitro-1H-imidazole is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-Fluorophenyl)-4-methyl-5-nitro-1H-imidazole (CAS 104575-41-9) is a high-purity analytical reference standard with the molecular formula C19H21ClFN3O3 and a molecular weight of 393.84 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-(4-Fluorophenyl)-4-methyl-5-nitro-1H-imidazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 393.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
