Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.08 g/mol gives (4-Fluorobenzofuran-2-yl)boronic acid pinacol ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (4-Fluorobenzofuran-2-yl)boronic acid pinacol ester (CAS 2121514-66-5), a certified reference material (molecular formula C14H16BFO3, MW 262.08 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (4-Fluorobenzofuran-2-yl)boronic acid pinacol ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
