(5-Ethyl-2-fluorophenyl)boronic acid (CAS 900175-03-3), molecular formula C8H10BFO2 and molecular weight 167.97 g/mol, is a CATO reference standard with documented purity and traceability.
(5-Ethyl-2-fluorophenyl)boronic acid (C8H10BFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
