Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 215.95 g/mol gives 4,5-Difluoro-2-(methoxycarbonyl)phenylboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,5-Difluoro-2-(methoxycarbonyl)phenylboronic acid (CAS 2096334-34-6) is a high-purity analytical reference standard with the molecular formula C8H7BF2O4 and a molecular weight of 215.95 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4,5-Difluoro-2-(methoxycarbonyl)phenylboronic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.95 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
