Description

2-Chloro-1,4-Phenylenediamine Sulfate is a specialized aromatic amine salt, primarily recognized as a key intermediate in the synthesis of advanced organic colorants. Its value lies in its role as a versatile building block for creating high-performance dyes and pigments with specific color fastness and stability properties. This compound is essential for manufacturers in the hair dye, textile dye, and specialty chemical industries seeking to develop or produce complex color molecules.

Application

• Primary Intermediate for Oxidative Hair Dyes: A crucial component in permanent hair color formulations, where it reacts with couplers to produce a wide spectrum of dark shades, particularly browns and blacks.
• Textile Dye Intermediate: Used in the synthesis of azo dyes and other complex dyes for coloring natural and synthetic fibers, offering good wash and light fastness.
• Polymer and Resin Colorant: Serves as a precursor for pigments used in plastics, coatings, and inks, where thermal stability and color consistency are required.
• Photographic Chemicals: Employed in the production of certain color-developing agents used in photographic and imaging applications.
• Research & Development: Used in organic synthesis laboratories as a reagent for constructing more complex heterocyclic and aromatic compounds.

Quality Control

Our 2-Chloro-1,4-Phenylenediamine Sulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for use in sensitive applications like hair dyes. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
