4,4,5,5-tetramethyl-2-(2,2,6,6-tetramethyl-3,6-dihydro-2H-pyran-4-yl)-1,3,2-dioxaborolane CAS 1142363-56-1 chemical structure

Description

The occurrence of 4,4,5,5-tetramethyl-2-(2,2,6,6-tetramethyl-3,6-dihydro-2H-pyran-4-yl)-1,3,2-dioxaborolane is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4,5,5-tetramethyl-2-(2,2,6,6-tetramethyl-3,6-dihydro-2H-pyran-4-yl)-1,3,2-dioxaborolane (CAS 1142363-56-1), molecular formula C15H27BO3 and molecular weight 266.18 g/mol, is a CATO reference standard with documented purity and traceability.

4,4,5,5-tetramethyl-2-(2,2,6,6-tetramethyl-3,6-dihydro-2H-pyran-4-yl)-1,3,2-dioxaborolane (C15H27BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
