Chemical Structure
Description
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.
4-(2-((3,5-Dimethylphenyl)amino)-2-oxoethyl)phenyl 2-methylbenzoate (CAS 439096-79-4), molecular formula C24H23NO3 and molecular weight 373.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(2-((3,5-Dimethylphenyl)amino)-2-oxoethyl)phenyl 2-methylbenzoate (C24H23NO3) is characterized by a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 4-(2-((3,5-Dimethylphenyl)amino)-2-oxoethyl)phenyl 2-methylbenzoate 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.
