4-((3,4-Dimethylphenyl)amino)-4-oxobutanoic acid (CAS 69517-61-9), molecular formula C12H15NO3 and molecular weight 221.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((3,4-Dimethylphenyl)amino)-4-oxobutanoic acid (C12H15NO3) 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 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
