Industrial Applications
This compound is primarily employed as a synthetic intermediate in the production of permanent and semi-permanent hair dyes. Its unique substitution pattern enables controlled coupling reactions with developers such as resorcinol or m-aminophenol under alkaline oxidative conditions, yielding stable indo dyes with desirable color tones ranging from golden to deep brown.
- Serves as a precursor for azo and indo dye chromophores
- Compatible with standard oxidative hair coloring systems
- Manufactured under ISO-compliant quality control protocols
- Supplied in 25 kg fiber drums or custom packaging upon request
For optimal stability, store in a cool, dry, and well-ventilated area away from direct sunlight and incompatible materials. Safety data sheets and certificates of analysis (COA) are available upon request to support regulatory compliance and formulation development.
