Description

2-(2-Hydroxyethyl)-p-Phenylenediamine is a specialized aromatic amine derivative featuring both a primary amine and a hydroxyethyl functional group. This bifunctional structure makes it a valuable intermediate for synthesizing high-performance polymers, dyes, and photographic chemicals. It is particularly sought after by manufacturers in the polymer, hair dye, and advanced material sectors for its role in creating colorants and cross-linking agents.

Application

• Polymer Industry: Key monomer for the synthesis of polyamides, polyurethanes, and epoxy curing agents, imparting flexibility and chemical resistance.
• Oxidative Hair Dyes: Primary intermediate in permanent hair color formulations, where it reacts to form a wide spectrum of dark shades.
• Photographic Chemicals: Used as a color developing agent in chromogenic film and paper processing.
• Textile Dyes and Pigments: Intermediate for manufacturing azo dyes and organic pigments for fibers and plastics.
• Pharmaceutical Synthesis: Building block for active pharmaceutical ingredients (APIs) and diagnostic agents.
• Corrosion Inhibitors: Component in formulations designed to protect metals in industrial fluids.
• Adhesives and Resins: Cross-linking agent that enhances the thermal and mechanical properties of adhesives and composite resins.

Quality Control

Our 2-(2-Hydroxyethyl)-p-Phenylenediamine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for critical applications like hair dyes and polymer synthesis. Certificates of Analysis (COA) documenting all test results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize degradation. Keep away from strong oxidizing agents.
