Chemical Structure
Description
The occurrence of 4-(((Benzyloxy)carbonyl)amino)-3-(4-chlorophenyl)butanoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(((Benzyloxy)carbonyl)amino)-3-(4-chlorophenyl)butanoic acid (CAS 78131-31-4), a certified reference material (molecular formula C18H18ClNO4, MW 347.79 g/mol) for analytical method development and quality control.
4-(((Benzyloxy)carbonyl)amino)-3-(4-chlorophenyl)butanoic acid (C18H18ClNO4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-(((Benzyloxy)carbonyl)amino)-3-(4-chlorophenyl)butanoic 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.
