Chemical Structure

(3,4-Di-sec-butoxyphenyl)boronic acid CAS 667933-70-2 chemical structure

Description

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.

CATO supplies (3,4-Di-sec-butoxyphenyl)boronic acid (CAS 667933-70-2), a certified reference material (molecular formula C14H23BO4, MW 266.14 g/mol) for analytical method development and quality control.

Structurally, (3,4-Di-sec-butoxyphenyl)boronic acid (C14H23BO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 266.14 g/mol, it falls into the medium-molecular-weight range. 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.
