Chemical Structure
Description
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.
4,5,6,7-Tetrafluoro-2-(perfluorophenyl)benzo[d][1,3,2]dioxaborole (CAS 365458-36-2), molecular formula C12BF9O2 and molecular weight 357.92 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,5,6,7-Tetrafluoro-2-(perfluorophenyl)benzo[d][1,3,2]dioxaborole (C12BF9O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 357.92 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
