Chemical Structure
Description
The occurrence of 4-Fluoro-3-(methoxycarbonyl)phenylboronic 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-3-(methoxycarbonyl)phenylboronic Acid (CAS 874219-35-9) is a high-purity analytical reference standard with the molecular formula C8H8BFO4 and a molecular weight of 197.96 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-Fluoro-3-(methoxycarbonyl)phenylboronic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 197.96 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.
As a certified reference material (CRM), 4-Fluoro-3-(methoxycarbonyl)phenylboronic Acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
