Dye — Azo
The synthesis of these dyes usually involves a two-step process:
: The diazonium salt acts as an electrophile, reacting with an electron-rich nucleophile (like a phenol or another aromatic amine) to create the final azo bond. Industrial and Biological Applications azo dye
Azo dyes are a dominant class of synthetic organic colorants, characterized by the presence of one or more ( The synthesis of these dyes usually involves a
Because they are highly versatile, azo dyes are used across a vast range of commercial sectors: Azo Dyes - an overview | ScienceDirect Topics This arrangement creates an extensive , which allows
: An aromatic amine reacts with nitrous acid at low temperatures to form a diazonium salt .
The defining feature of an azo dye is the azo linkage connecting two aromatic fragments, typically aryl groups. This arrangement creates an extensive , which allows the molecule to absorb energy in the visible light spectrum (400–800 nm), resulting in intense, stable colors.
