Azo dye - Wikipedia
Azo dyes are organic compounds bearing the functional group R−N=N−R′, in which R and R′ are usually aryl and substituted aryl groups. They are a commercially important family of azo compounds, i.e. compounds containing the C−N=N−C linkage. [1] .
Azo Dye - an overview | ScienceDirect Topics
Azo dyes are widely used in the food, pharmaceutical, cosmetic, textile, and leather industries. They are synthetic compounds characterized by one (monoazo) or several intramolecular NQN bonds. Azo dyes, if they are systemically absorbed, can be metabolized via azoreductases of intestinal microflora by liver cells and skin surface bacteria ...
Classifications, properties, recent synthesis and applications of azo dyes
Azo dyes represent the largest production volume of dye chemistry today, and their relative importance may even increase in the future. They play a crucial role in the governance of the dye and printing market. These dyes are synthesized from …

Azo Compounds: Preparation, Types, Properties - Science Info
2023年6月9日 · Azo dyes are the most significant category of synthetic colorants and the most prevalent class of dyes in use today. There are different systems of classification for azo dyes. Disperse dyes, such as Disperse Orange, are included in some classes.
One of most widespread class of synthetic dyes is azo dyes. Since the discovery of diazo compounds by Peter Greiss in 1858, series of different types of azo dyes have been synthesized and marketed.
Azo compound - Wikipedia
Azo compounds are organic compounds bearing the functional group diazenyl (R−N=N−R′, in which R and R′ can be either aryl or alkyl groups).
Chemistry and Applications of Azo Dyes: A Comprehensive Review
Azo dyes are substances with one or more azo groups (-N=N-) coupled with two mono- or polycyclic aromatic systems in their structure. Unlike most organic compounds, azo dyes possess color; as a result, azo compounds have various usages.
The chemistry of azo dyes | SpringerLink
Azo dyes are characterised by presence in the molecule of one or more azo groups —N = N—, which form bridges between organic residues, of which at least one is usually an aromatic nucleus. Many methods are available for preparing azo compounds, but...
