Is azo dye and diazo compound same thingh?
No, azo dyes are a type of synthetic dye characterized by the azo group (-N=N-) in their molecular structure, while diazo compounds are a class of organic compounds that contain the diazo group (-N=N-). Azo dyes are a specific application of diazo compounds in dye chemistry, but not all diazo compounds are azo dyes.
Would water be a suiable solvent for every dye?
-Cationic dyes (basic dyes) are soluble in polar solvents such as water, alcohols -Nonionic Fat-soluble dyes line metal-free azo and anthraquinone dyes are soluble in aromatic and aliphatic hydrocarbons. -Metal-complex dyes are normally soluble in alcohols, ketones, glycoethers
What are the Pharmacological uses of 4-nitrobenzene azo naphthol?
4-nitrobenzene azo naphthol is commonly used as a dye in histological staining procedures for identifying and visualizing specific structures under a microscope. Additionally, it has also been studied for its potential in developing selective and sensitive sensors for metal ions due to its complexation properties.
Mechanism of azo dye Para Red synthesis?
Azo food dyes don't set off allergic reactions as such, though some azo textile dyes can cause your skin to be hypersensitive. The mechanism for why tartrazine increases allergic reactions is not yet known.

What is azo dye test?
Azo dye test is the chemical test to identify the release of banned amines from any nitrogen based azo -synthetic dyes . There is a limit of 30 ppm for the banned amines in any textile or leather article which may come in contact with skin
What do you mean by restricted azo dye?
Restricted azo dyes are a type of synthetic dye commonly used in the textile industry. These dyes have restricted chemical properties and are subject to specific regulations due to their potential to release harmful substances such as aromatic amines, which can be carcinogenic. Manufacturers must comply with strict guidelines to ensure restricted azo dyes are safely used in products.
Does acridine dye is azo dye?
An acridine dye can be only an azo dye if you have an azo bridge like -N=N- in your dye. For an acridine azo dye you must have a free amino group on it. Your question is not right formulated. I need more infos in order to give a right answer
What is an azo dye?
An azo dye is any of a number of yellow to red synthetic dyes which contain an azo or diimide functional group.

What would be the IUPAC name for azo dye using p-chloroaniline instead of sulfanilic acid?
4-[(2-hydroxy-1-naphthalenyl)azo]phenyl chloride monosodium salt
What happens when benzene diazonium chloride is treated with alkaline 2-naphthol?
When benzene diazonium chloride is treated with alkaline 2-naphthol, a diazo-coupling reaction occurs. This results in the formation of an azo dye, specifically the orange-red compound called Sudan I. This reaction is commonly used for the synthesis of azo dyes in organic chemistry.
Why aromatic ring is present in all dyes structure?
Aromatic rings are commonly found in dye molecules because they provide stability and color properties to the dye molecule. The conjugated pi electrons in the aromatic ring system allow for absorption and reflection of specific wavelengths of light, resulting in the characteristic color of the dye. Additionally, aromatic rings can easily bind to substrates, such as fabrics, making them ideal for use in dyeing processes.
