Product Overview
Our facility specializes in the premium production of 4,5-Diamino-1-(2-Hydroxyethyl)pyrazole Sulfate, a critical chemical building block extensively utilized in the modern cosmetic industry. This compound serves as a foundational intermediate for the synthesis of high-performance hair coloring agents. Manufactured under strict Good Manufacturing Practices (GMP), our product ensures exceptional batch-to-batch consistency, which is vital for formulators requiring reliable color development and stability in their final formulations.
The chemical structure of this pyrazole derivative offers superior solubility characteristics due to its sulfate salt form, facilitating easier integration into aqueous-based dye systems. We understand that impurities can significantly affect the hue and safety profile of cosmetic products. Therefore, our production process emphasizes high purification standards to minimize unwanted by-products and heavy metal contaminants.
Key Specifications
Quality control is the cornerstone of our manufacturing philosophy. Each batch undergoes rigorous analytical testing using High-Performance Liquid Chromatography (HPLC) and other advanced spectroscopic methods. The following table outlines the standard technical parameters that define our commercial grade material:
| Parameter | Specification |
|---|---|
| Appearance | White to light pink crystalline powder |
| Purity (HPLC) | ≥99.0% |
| Moisture Content | ≤0.5% |
| Residue on Ignition (Ash) | ≤0.5% |
| Iron (Fe) Content | ≤50 ppm |
| Molecular Formula | C5H12N4O5S |
| Molecular Weight | 240.24 g/mol |
Industrial Applications
This intermediate is primarily engineered for use in the personal care sector, specifically within oxidative hair dye formulations. The diamino pyrazole structure acts as a key coupler or primary intermediate, reacting with oxidants to generate stable colorants that penetrate the hair shaft effectively. Its low iron content is particularly crucial, as trace metals can catalyze unwanted oxidation reactions, leading to color shifts or instability during storage.
- Compatible with various oxidative dye systems
- Enhances color fastness and vibrancy
- Optimized for large-scale industrial mixing
- Supports consistent shade reproduction
