Compared with other compounds in its class, the molecular weight of 242.08 g/mol gives (5-(Benzyloxy)-2-methylphenyl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(5-(Benzyloxy)-2-methylphenyl)boronic acid (CAS 1451391-56-2) is a high-purity analytical reference standard with the molecular formula C14H15BO3 and a molecular weight of 242.08 g/mol.
The molecular framework of (5-(Benzyloxy)-2-methylphenyl)boronic acid (C14H15BO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
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.
As a certified reference material (CRM), (5-(Benzyloxy)-2-methylphenyl)boronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
