The occurrence of 4-Carboxy-3-fluorobenzeneboronic acid pinacol ester, 97% is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Carboxy-3-fluorobenzeneboronic acid pinacol ester, 97% (CAS 867256-77-7) is a high-purity analytical reference standard with the molecular formula C13H16BFO4 and a molecular weight of 266.07 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Carboxy-3-fluorobenzeneboronic acid pinacol ester, 97% is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
