Chemical Structure

2-(2,3-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane CAS 1232132-73-8 chemical structure

Description

2-(2,3-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 1232132-73-8), molecular formula C14H21BO2 and molecular weight 232.13 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H21BO2, 2-(2,3-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 232.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
