Chemical Structure
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.
(3,5-Di-tert-butyl-4-hydroxyphenyl)boronic acid (CAS 182344-15-6), molecular formula C14H23BO3 and molecular weight 250.14 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H23BO3, (3,5-Di-tert-butyl-4-hydroxyphenyl)boronic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.14 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.
