At NINGBO INNO PHARMCHEM CO.,LTD., precision and quality are paramount in the chemicals we supply. This article provides a detailed look at the technical specifications of N,N-Bis(2-hydroxyethyl)-p-phenylenediamine Sulphate, a critical component for the hair dye and cosmetic industries, and touches upon its broader chemical synthesis applications.

N,N-Bis(2-hydroxyethyl)-p-phenylenediamine Sulphate, identified by CAS number 54381-16-7, is characterized by its specific physical and chemical properties that dictate its utility. The material typically presents as a light grey crystalline powder. Its physical state is important for handling and formulation processes within manufacturing settings.

Key technical specifications include its purity, which is essential for consistent performance in end products. Our N,N-Bis(2-hydroxyethyl)-p-phenylenediamine Sulphate boasts a purity of ≥99.0% as determined by HPLC (High-Performance Liquid Chromatography), ensuring minimal presence of impurities that could affect its performance as a hair dye intermediate or its stability as an antioxidant in hair colorants.

Further critical physical properties include:

  • Melting Point: 168-171°C. This indicates the temperature range at which the solid transitions to a liquid, crucial for understanding its thermal stability during processing.
  • Boiling Point: 416.4°C. While not typically relevant for its use in hair dyes at room temperature, it provides insight into its thermal behavior at higher temperatures.
  • Flash Point: 205.6°C. This safety parameter indicates the minimum temperature at which the substance's vapors can ignite in the presence of an ignition source.
  • Ash Content: ≤0.5%. This measures the inorganic residue remaining after combustion, signifying the level of inorganic impurities.
  • Moisture Content: ≤3-7%. Controlling moisture is vital for the stability and shelf-life of the powder.
  • Iron Content: ≤50ppm. Trace metals like iron can sometimes catalyze unwanted reactions, so low iron content is desirable.

These detailed specifications ensure that manufacturers using N,N-Bis(2-hydroxyethyl)-p-phenylenediamine Sulphate receive a product that meets the stringent demands of their formulations. As a key reducing agent for hair dyes, its purity and consistent physical properties are non-negotiable for achieving reliable color results.

The demand for this compound is robust, driven by the dynamic hair color market and its potential pharmaceutical applications of diamine sulphate compounds. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying this vital chemical with adherence to these precise technical standards, supporting our clients in producing high-quality and effective products.

In conclusion, the technical profile of N,N-Bis(2-hydroxyethyl)-p-phenylenediamine Sulphate highlights its importance as a high-purity chemical intermediate.
