What Is Benzenemethanaminium_, N-_ethyl-_N-_[4-_[[4-_[ethyl[(3-_sulfophenyl)_methyl]_amino]_phenyl]_(4-_hydroxy-_2-_sulfophenyl)_methylene]_-_2,_5-_cyclohexadien-_1-_ylidene]_-_3-_sulfo-_, inner salt, sodium salt (1:2)?

This synthetic compound is primarily encountered in industrial applications and specialized colorants rather than consumer fragrances. Its complex structure makes it unsuitable for direct scent applications. While not commonly used in perfumery, it serves as a model for understanding how molecular architecture influences color and potential odor profiles in advanced materials.

This compound does not have documented odor characteristics for perfumery applications. Its complex sulfonated structure suggests it would be odorless or have minimal volatile components at standard conditions. The multiple charged groups and high molecular weight make evaporation unlikely under normal fragrance usage scenarios.

Chemistry, Properties & Perfumer Guide

The Chemistry

This is a synthetic sulfonated triarylmethane dye derivative with multiple charged groups. The structure features three aromatic rings connected through nitrogen and carbon centers, with sulfonate groups providing water solubility. As an inner salt sodium complex, it exists as a zwitterion in solution. Industrial synthesis typically involves multi-step condensation reactions of aromatic amines with formaldehyde derivatives followed by sulfonation.
