Chemical Structure
Description
CATO supplies (4-((2-Cyanobenzyl)oxy)phenyl)boronic acid (CAS 1256358-43-6), a certified reference material (molecular formula C14H12BNO3, MW 253.06 g/mol) for analytical method development and quality control.
(4-((2-Cyanobenzyl)oxy)phenyl)boronic acid (C14H12BNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (4-((2-Cyanobenzyl)oxy)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.
