Chemical Structure
Description
The occurrence of 5-Bromo-2-chloro-4-ethoxypyridine is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-2-chloro-4-ethoxypyridine (CAS 52311-48-5) is a high-purity analytical reference standard with the molecular formula C7H7BrClNO and a molecular weight of 236.49 g/mol.
5-Bromo-2-chloro-4-ethoxypyridine (C7H7BrClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
