Description

Tetrasodium Naphthalene-1,3,5,7-Tetrasulphonate is a high-purity, water-soluble aromatic sulfonate salt. This compound is valued for its exceptional ability to function as a dispersant, complexing agent, and dye intermediate in demanding industrial processes. It is a critical material for manufacturers in the textile, construction, and specialty chemical sectors who require reliable performance and consistent quality.

Application

• Dye Intermediate & Dispersant: A key building block and dispersing agent in the synthesis of acid, direct, and reactive dyes, ensuring uniform color distribution.
• Concrete & Cement Admixture: Acts as a highly effective superplasticizer and water-reducing agent to improve workability and strength of concrete mixes.
• Textile Auxiliary: Used in dyeing and printing processes to enhance dye solubility, levelness, and fastness properties on various fabrics.
• Scale Inhibitor & Dispersant: Prevents the precipitation and deposition of inorganic scales (e.g., calcium carbonate, sulfate) in industrial water treatment and cooling systems.
• Ceramic & Pigment Processing: Improves the rheology and stability of slurries, aiding in the uniform dispersion of inorganic particles.
• Oilfield Chemical: Employed in drilling mud formulations as a thinner and dispersant to control rheology and fluid loss.
• Electroplating Additive: Serves as a brightener and complexing agent in electroplating baths to improve deposit quality.
• Research & Development: Used in chemical synthesis and material science research as a polyfunctional sulfonating agent or template.

Quality Control

Our Tetrasodium Naphthalene-1,3,5,7-Tetrasulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, solubility, and performance. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is available for each shipment to support your quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
