Chemical Structure
Description
The occurrence of [3,5-Bis(benzyloxy)phenyl]boronic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
[3,5-Bis(benzyloxy)phenyl]boronic acid (CAS 906665-99-4) is a high-purity analytical reference standard with the molecular formula C20H19BO4 and a molecular weight of 334.17 g/mol.
The molecular framework of [3,5-Bis(benzyloxy)phenyl]boronic acid (C20H19BO4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), [3,5-Bis(benzyloxy)phenyl]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.
