Chemical Structure

8-Bromo-3-chloro-4-quinolinol CAS 1204810-71-8 chemical structure

Description

The occurrence of 8-Bromo-3-chloro-4-quinolinol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

8-Bromo-3-chloro-4-quinolinol (CAS 1204810-71-8) is a high-purity analytical reference standard with the molecular formula C9H5BrClNO and a molecular weight of 258.50 g/mol.

8-Bromo-3-chloro-4-quinolinol (C9H5BrClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; 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.
