Chemical Structure
Description
The molecular framework of 4-Anilino-4-oxobutanoic acid-d5 (C10H6D5NO3) is characterized by deuterium isotope labeling, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
4-Anilino-4-oxobutanoic acid-d5 (CAS 840529-98-8), molecular formula C10H6D5NO3 and molecular weight 198.23 g/mol, is a CATO reference standard with documented purity and traceability.
