Chemical Structure
Description
4,4,5,5-Tetramethyl-2-(6-methyl-1-cyclohexen-1-yl)-1,3,2-dioxaborolane (CAS 448211-44-7), molecular formula C13H23BO2 and molecular weight 222.13 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,4,5,5-Tetramethyl-2-(6-methyl-1-cyclohexen-1-yl)-1,3,2-dioxaborolane (C13H23BO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 222.13 g/mol, it falls into the medium-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.
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.
