Chemical Structure

4,4,5,5-Tetramethyl-2-(pentan-3-yl)-1,3,2-dioxaborolane CAS 1346264-22-9 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 4,4,5,5-Tetramethyl-2-(pentan-3-yl)-1,3,2-dioxaborolane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.11 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.

CATO supplies 4,4,5,5-Tetramethyl-2-(pentan-3-yl)-1,3,2-dioxaborolane (CAS 1346264-22-9), a certified reference material (molecular formula C11H23BO2, MW 198.11 g/mol) for analytical method development and quality control.

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.
