4- NITRO META PHENYLENE DIAMINE

4-Nitro-m-Phenylene Diamine (4-NMPD) is a specialized aromatic amine widely used as an intermediate in dye manufacturing and hair dye formulations. Known for its reactivity and compatibility, it plays a vital role in producing vibrant and stable dyes for textiles, hair, and industrial applications. Available as a yellow to brown crystalline powder, 4-NMPD is a key component in the synthesis of azo dyes and pigments.

Applications

1. Dye Manufacturing

4-NMPD is a critical intermediate in the production of azo dyes and pigments, which are extensively used in textiles, leather, and plastics industries.

2. Hair Dye Formulations

It is used as a precursor in oxidative hair dyes, contributing to rich and lasting color tones. 4-NMPD is known for its role in creating natural-looking shades with high stability.

3. Industrial Coloring

Utilized in the synthesis of dyes for industrial coatings, inks, and other colorant products, offering excellent performance in varied applications.

4. Research and Development

4-NMPD is employed in chemical research and development for studying new dye formulations and industrial processes.

5. Cosmetic Applications

Apart from hair dyes, it finds limited use in certain cosmetic products that require specific dye properties.

Safety and Handling

Precautions

• Personal Protective Equipment (PPE):
  • Wear gloves, goggles, and protective clothing to avoid skin and eye contact.
  • Use a dust mask or respirator to prevent inhalation of powders.
• Storage:
  • Store in a cool, dry, and well-ventilated area.
