Description

Calcium 1-Amino-4-[(5-Chloro-4-Methyl-2-Sulphonatophenyl)Azo]Naphthalene-2-Sulphonate is a high-purity, water-soluble azo dye intermediate essential for producing vivid and stable colorants. Its value lies in its consistent chemical structure, which ensures reliable performance in demanding synthesis processes where color fastness and purity are critical. This compound is primarily needed by manufacturers in the textile dyeing, ink formulation, and specialty pigment industries seeking to develop high-quality red to violet shades.

Application

• Primary Intermediate for Azo Dyes: A key building block in the synthesis of direct, acid, and reactive dyes, particularly for cotton, wool, and nylon.
• Textile Colorant Production: Used to manufacture dyes that impart red, bordeaux, or violet hues with good wash and light fastness.
• Ink and Pigment Manufacturing: Serves as a precursor for colorants used in printing inks, leather dyes, and paper coloration.
• Research & Development: Employed in chemical R&D for developing new chromophores and studying azo dye chemistry and properties.
• Specialty Chemical Synthesis: May be used as an intermediate for more complex, high-value dyes and functional chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance and handling.
