(E)-4,4,5,5-Tetramethyl-2-(3-methylpent-1-en-1-yl)-1,3,2-dioxaborolane CAS 157945-81-8

Description

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.

(E)-4,4,5,5-Tetramethyl-2-(3-methylpent-1-en-1-yl)-1,3,2-dioxaborolane (CAS 157945-81-8), molecular formula C12H23BO2 and molecular weight 210.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-4,4,5,5-Tetramethyl-2-(3-methylpent-1-en-1-yl)-1,3,2-dioxaborolane (C12H23BO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
