4,4 inverted exclamation marka-(Phenylimino)bisbenzaldehyde 4,4 inverted exclamation marka-Diformyltriphenylamine 53566-95-3 Bis(4-formylphenyl)aniline Bis(4-formylphenyl)phenylamine (CAS 53566-95-3), molecular formula C20H33NO2 and molecular weight 319.48 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4 inverted exclamation marka-(Phenylimino)bisbenzaldehyde 4,4 inverted exclamation marka-Diformyltriphenylamine 53566-95-3 Bis(4-formylphenyl)aniline Bis(4-formylphenyl)phenylamine (C20H33NO2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
