Description
CATO manufactures 4-Ethoxycarbonyl-3-fluorophenylboronic acid pinacol ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 4-Ethoxycarbonyl-3-fluorophenylboronic acid pinacol ester (CAS 474709-72-3), a certified reference material (molecular formula C15H20BFO4, MW 294.13 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H20BFO4, 4-Ethoxycarbonyl-3-fluorophenylboronic acid pinacol ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 294.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
