Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Chloro-4-ethoxyphenylboronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.43 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).
2-Chloro-4-ethoxyphenylboronic acid (CAS 313545-44-7), molecular formula C8H10BClO3 and molecular weight 200.43 g/mol, is a CATO reference standard with documented purity and traceability.
