Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4,4,5,5-Tetramethyl-2-[4-(1-methylethyl)-1-cyclohexen-1-yl]-1,3,2-dioxaborolane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4,4,5,5-Tetramethyl-2-[4-(1-methylethyl)-1-cyclohexen-1-yl]-1,3,2-dioxaborolane (CAS 1591906-87-4) is a high-purity analytical reference standard with the molecular formula C15H27BO2 and a molecular weight of 250.18 g/mol.
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.
