Chemical Structure
Description
The occurrence of 4-Fluoro-5-formyl-2-methylphenylboronic acid 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-Fluoro-5-formyl-2-methylphenylboronic acid (CAS 2377606-69-2) is a high-purity analytical reference standard with the molecular formula C8H8BFO3 and a molecular weight of 181.96 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Fluoro-5-formyl-2-methylphenylboronic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 181.96 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).
