Chemical Structure
Description
4,4,5,5-Tetramethyl-2-(3,3,3-trifluoropropyl)-1,3,2-dioxaborolane (CAS 1148113-74-9), molecular formula C9H16BF3O2 and molecular weight 224.03 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H16BF3O2, 4,4,5,5-Tetramethyl-2-(3,3,3-trifluoropropyl)-1,3,2-dioxaborolane contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 224.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
