Chemical Structure
Description
2-Fluoro-3-methylbenzeneboronic acid pinacol ester, 97% (CAS 1192548-08-5) is a high-purity analytical reference standard with the molecular formula C13H18BFO2 and a molecular weight of 236.09 g/mol.
The molecular framework of 2-Fluoro-3-methylbenzeneboronic acid pinacol ester, 97% (C13H18BFO2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-Fluoro-3-methylbenzeneboronic acid pinacol ester, 97% 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.
