Chemical Structure
Description
(E)-(3-Fluorostyryl)boronic Acid (CAS 849062-22-2) is a high-purity analytical reference standard with the molecular formula C8H8BFO2 and a molecular weight of 165.96 g/mol.
The molecular framework of (E)-(3-Fluorostyryl)boronic Acid (C8H8BFO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (E)-(3-Fluorostyryl)boronic 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.
