Chemical Structure
Description
(E)-6-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)hex-5-en-1-yl acetate (CAS 581802-23-5), molecular formula C14H25BO4 and molecular weight 268.16 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H25BO4, (E)-6-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)hex-5-en-1-yl acetate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 268.16 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.
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.
