2-FLUORO-4-ETHOXYPHENYLBORONIC ACID 279261-82-4 4-ETHOXY-2-FLUOROPHENYLBORONIC ACID BC001180 BORONIC ACID, (4-ETHOXY-2-FLUOROPHENYL)- (CAS 279261-82-4), molecular formula C8H10BFO3 and molecular weight 183.97 g/mol, is a CATO reference standard with documented purity and traceability.
2-FLUORO-4-ETHOXYPHENYLBORONIC ACID 279261-82-4 4-ETHOXY-2-FLUOROPHENYLBORONIC ACID BC001180 BORONIC ACID, (4-ETHOXY-2-FLUOROPHENYL)- (C8H10BFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), 2-FLUORO-4-ETHOXYPHENYLBORONIC ACID 279261-82-4 4-ETHOXY-2-FLUOROPHENYLBORONIC ACID BC001180 BORONIC ACID, (4-ETHOXY-2-FLUOROPHENYL)- 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.
