Chemical Structure
Description
The occurrence of 2,3,4,5,6-Pentamethylphenylboronic Acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,3,4,5,6-Pentamethylphenylboronic Acid (CAS 1028205-76-6), molecular formula C11H17BO2 and molecular weight 192.06 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H17BO2, 2,3,4,5,6-Pentamethylphenylboronic 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 192.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
