Chemical Structure
Description
Based on its molecular formula C12H17BO3, 3-[(Cyclopentyloxy)methyl]phenylboronic acid 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 220.07 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).
3-[(Cyclopentyloxy)methyl]phenylboronic acid (CAS 1334218-46-0), molecular formula C12H17BO3 and molecular weight 220.07 g/mol, is a CATO reference standard with documented purity and traceability.
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.
