Description
CATO supplies 2-((tert-Butoxycarbonyl)amino)-3-(4-((2,6-dichlorobenzyl)oxy)phenyl)propanoic acid (CAS 201334-88-5), a certified reference material (molecular formula C21H23Cl2NO5, MW 440.32 g/mol) for analytical method development and quality control.
2-((tert-Butoxycarbonyl)amino)-3-(4-((2,6-dichlorobenzyl)oxy)phenyl)propanoic acid (C21H23Cl2NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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), 2-((tert-Butoxycarbonyl)amino)-3-(4-((2,6-dichlorobenzyl)oxy)phenyl)propanoic 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.
