(E)-Ethyl 2,2-difluoro-3-(5-methyl-2-((2-methylallyl)oxy)phenyl)-3-(2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)propanoate (CAS 2738683-69-5), molecular formula C23H23F5N2O5S and molecular weight 534.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-Ethyl 2,2-difluoro-3-(5-methyl-2-((2-methylallyl)oxy)phenyl)-3-(2-((2-(trifluoromethyl)phenyl)sulfonyl)hydrazono)propanoate (C23H23F5N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
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.
