Azoxy compounds. The structure of the azoxy functional group, where R is a substituent. In chemistry, azoxy compounds are a group of organic compounds sharing a common functional group with the general structure R−N=N+(−O−)−R. [1] They are considered N-oxides of azo compounds. Azoxy compounds are 1,3-dipoles and cycloadd to double bonds.
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 dyes are synthetic dyes and do not occur naturally. [ 2][ 3] Most azo dyes contain only ...
Azo violet ( Magneson I; [ 1] p-nitrobenzeneazoresorcinol) is an azo compound with the chemical formula C 12 H 9 N 3 O 4. It is used commercially as a violet dye and experimentally as a pH indicator, appearing yellow below pH 11, and violet above pH 13. [ 2] It also turns deep blue in the presence of magnesium salt in a slightly alkaline, or ...

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). IUPAC defines azo compounds as: "Derivatives of diazene (diimide), HN=NH , wherein both hydrogens are substituted by hydrocarbyl groups, e.g. PhN=NPh azobenzene or diphenyldiazene.", where Ph stands ...

Direct Blue 1 is an organic compound that is one of many azo dyes. This salt is used as a substantive dye for textiles with high contents of cellulose, i.e. cotton. It is prepared by the azo coupling of the aminonaphthalene and diazotized derivative of o -dianisidine. [2]
