Chemical Structure
Description
2-(3-Fluorophenyl)-1,3,2-dioxaborolane (CAS 718642-08-1) is a high-purity analytical reference standard with the molecular formula C8H8BFO2 and a molecular weight of 165.96 g/mol.
2-(3-Fluorophenyl)-1,3,2-dioxaborolane (C8H8BFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
