Product Parameters

 

Primary Intrduction of 4-Amino-3-nitrophenol CAS 610-81-1 :

This compound is a versatile and important bifunctional dye intermediate.

• Azo Dye & Pigment Synthesis:

  • As a Coupling Component: Its phenolic -OH group can couple with diazonium salts to produce hydroxyazo dyes, often yielding yellow, orange, or brown shades.

  • As a Diazo Component: Its aromatic amine can be diazotized and coupled to other components (like naphthols or pyrazolones) to produce azo dyes.

  • This dual functionality allows it to be used in the synthesis of disazo and polyazo dyes, contributing to deeper shades (e.g., blacks, navies, browns) with good properties.

• Hair Dye Intermediate: Used in oxidative permanent hair color formulations as a primary intermediate (developer), where it helps create reddish-golden to brown shades.

• Agrochemical Intermediate: Serves as a building block for more complex molecules.
