Chemical Structure
Description
The occurrence of 2-Methoxy-5-(4-pyridinyl)phenylboronic acid, 97% is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Methoxy-5-(4-pyridinyl)phenylboronic acid, 97% (CAS 196861-33-3), a certified reference material (molecular formula C12H12BNO3, MW 229.04 g/mol) for analytical method development and quality control.
The molecular framework of 2-Methoxy-5-(4-pyridinyl)phenylboronic acid, 97% (C12H12BNO3) is characterized by an amino-acid-derived structure, an amide group, 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 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).
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), 2-Methoxy-5-(4-pyridinyl)phenylboronic acid, 97% 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.
