Chemical Structure
Description
The occurrence of (4-(2-Ethoxy-1,1-difluoro-2-oxoethyl)phenyl)boronic 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-(2-Ethoxy-1,1-difluoro-2-oxoethyl)phenyl)boronic acid (CAS 1256345-83-1) is a high-purity analytical reference standard with the molecular formula C10H11BF2O4 and a molecular weight of 244.00 g/mol.
(4-(2-Ethoxy-1,1-difluoro-2-oxoethyl)phenyl)boronic acid (C10H11BF2O4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures (4-(2-Ethoxy-1,1-difluoro-2-oxoethyl)phenyl)boronic acid 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.
