4-((4-(Methoxycarbonyl)phenyl)amino)-4-oxobutanoic acid CAS 172982-81-9

Description

The occurrence of 4-((4-(Methoxycarbonyl)phenyl)amino)-4-oxobutanoic acid 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 4-((4-(Methoxycarbonyl)phenyl)amino)-4-oxobutanoic acid (CAS 172982-81-9), a certified reference material (molecular formula C12H13NO5, MW 251.24 g/mol) for analytical method development and quality control.

The molecular framework of 4-((4-(Methoxycarbonyl)phenyl)amino)-4-oxobutanoic acid (C12H13NO5) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
