Chemical Structure
Description
The occurrence of 3-Benzyloxyphenylboronic acid mida ester is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Benzyloxyphenylboronic acid mida ester (CAS 1356823-23-8), a certified reference material (molecular formula C18H18BNO5, MW 339.15 g/mol) for analytical method development and quality control.
The molecular framework of 3-Benzyloxyphenylboronic acid mida ester (C18H18BNO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-Benzyloxyphenylboronic acid mida ester 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.
