Chemical Structure
Description
The occurrence of (4-Chlorostyryl)boronic acid is closely related to 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.
(4-Chlorostyryl)boronic acid (CAS 214907-27-4) is a high-purity analytical reference standard with the molecular formula C8H8BClO2 and a molecular weight of 182.41 g/mol.
(4-Chlorostyryl)boronic acid (C8H8BClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
