For R&D scientists and product formulators in the cosmetic industry, understanding the chemical behavior of key ingredients is fundamental to innovation. This article delves into the utility of 4-nitroaniline derivatives, with a particular focus on 4-Nitro-1,3-phenylenediamine Sulfate (CAS: 200295-57-4), and how its specific characteristics contribute to advanced hair dye formulations. By carefully selecting and utilizing such intermediates, formulators can achieve superior color results and product efficacy.

The Chemical Profile of 4-Nitro-1,3-phenylenediamine Sulfate
4-Nitro-1,3-phenylenediamine Sulfate is characterized by its molecular formula C6H9N3O6S and its common presentation as a yellow crystalline powder. Its significance in hair dye chemistry lies in the nitro and diamine functional groups, which are crucial for the oxidative dyeing process. The sulfate salt form often enhances its stability and handling properties. Its high boiling point, noted at 648.6°C, suggests a robust chemical structure that can withstand typical processing conditions in dye manufacturing. As a reliable raw material, understanding its chemical reactivity is key for effective product development.

Impact on Hair Dye Performance
The purity of 4-Nitro-1,3-phenylenediamine Sulfate, a key metric for R&D professionals, directly correlates with the vibrancy, longevity, and consistency of hair colors. An intermediate with ≥99.0% purity, as offered by specialized chemical suppliers, minimizes the presence of impurities that could lead to duller shades, uneven color deposition, or adverse reactions. Furthermore, low moisture content (≤0.5%) contributes to the overall stability of the formulation, preventing degradation during storage and ensuring the product performs as expected upon purchase by the end consumer. Scientists looking to buy this intermediate can leverage these properties to achieve precise color outcomes.

Sourcing Strategies for R&D Chemists
When sourcing specialty chemicals like 4-Nitro-1,3-phenylenediamine Sulfate for research and development, R&D chemists should focus on suppliers who offer:

  • Technical Data Sheets (TDS) and Certificates of Analysis (CoA): Detailed documentation is essential for understanding the chemical's properties and ensuring it meets project requirements.
  • Small Batch Availability: For R&D purposes, the ability to purchase smaller quantities is often necessary for testing and formulation trials.
  • Supplier Reputation: Partnering with established manufacturers in China known for their quality control provides confidence in the material's consistency.
  • Inquiry for Pricing: Obtaining price quotes helps in budgeting for R&D projects and comparing potential suppliers.
