(E)-3-((3-chloro-4-methoxyphenyl)amino)-1-(3-((2,4-dichlorobenzyl)oxy)phenyl)prop-2-en-1-one (CAS 478040-11-8), molecular formula C23H18Cl3NO3 and molecular weight 462.75 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-3-((3-chloro-4-methoxyphenyl)amino)-1-(3-((2,4-dichlorobenzyl)oxy)phenyl)prop-2-en-1-one (C23H18Cl3NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 462.75 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
