Description

Sodium 2,6-Diaminotoluene-3-Sulphonate is a high-purity, water-soluble aromatic sulfonate salt, primarily used as a key intermediate in the synthesis of advanced organic pigments and dyes. Its value lies in providing the essential diaminotoluene backbone and sulfonate group for creating colorants with excellent stability, brightness, and application properties. This compound is critically needed by manufacturers in the pigment, dye, and specialty chemical industries for producing high-performance products for inks, coatings, and plastics.

Application

• Primary Intermediate for Organic Pigments: A crucial building block in the synthesis of high-performance azo and polycyclic pigments, particularly yellows, oranges, and reds.
• Dye Manufacturing: Used in the production of acid dyes and direct dyes for textiles, leather, and paper.
• Specialty Chemical Synthesis: Serves as a precursor for functional chemicals used in liquid crystal displays (LCDs) and electronic materials.
• Research & Development: An important reagent in academic and industrial R&D for developing novel chromophores and functional molecules.
• Ink Formulations: Contributes to the production of colorants for industrial and printing inks, offering good solubility and color strength.
• Polymer Additives: Can be incorporated into polymers to introduce specific functional groups or color properties.

Quality Control

Our Sodium 2,6-Diaminotoluene-3-Sulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications for consistent performance as a synthesis intermediate. Certificates of Analysis (COA) documenting purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
