Chemical Structure
Description
Based on its molecular formula C14H18BFO3, 1-[5-Fluoro-2-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]ethan-1-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1-[5-Fluoro-2-(tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]ethan-1-one (CAS 2377610-69-8), molecular formula C14H18BFO3 and molecular weight 264.10 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
