Chemical Structure
Description
4,4,5,5-Tetramethyl-2-(1-(tetrahydro-2H-pyran-4-yl)vinyl)-1,3,2-dioxaborolane (CAS 1202245-67-7) is a high-purity analytical reference standard with the molecular formula C13H23BO3 and a molecular weight of 238.13 g/mol.
4,4,5,5-Tetramethyl-2-(1-(tetrahydro-2H-pyran-4-yl)vinyl)-1,3,2-dioxaborolane (C13H23BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
