Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(2,4-Dinitrophenyl)pyridin-1-ium Chloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.65 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).
1-(2,4-Dinitrophenyl)pyridin-1-ium Chloride (CAS 4185-69-7) is a high-purity analytical reference standard with the molecular formula C11H8N3O4Cl and a molecular weight of 281.65 g/mol.
