(5Z,8Z,11Z,14Z)-N-(3-Nitrophenyl)icosa-5,8,11,14-tetraenamide (CAS 1175954-87-6), molecular formula C26H36N2O3 and molecular weight 424.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5Z,8Z,11Z,14Z)-N-(3-Nitrophenyl)icosa-5,8,11,14-tetraenamide (C26H36N2O3) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
