Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Fluoro-2-methoxybenzeneboronic acid pinacol ester, 97%.
CATO supplies 4-Fluoro-2-methoxybenzeneboronic acid pinacol ester, 97% (CAS 624741-83-9), a certified reference material (molecular formula C13H18BFO3, MW 252.09 g/mol) for analytical method development and quality control.
4-Fluoro-2-methoxybenzeneboronic acid pinacol ester, 97% (C13H18BFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4-Fluoro-2-methoxybenzeneboronic 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.
