Description

Trisodium Naphthalene-1,3,7-Trisulphonate is a high-purity, water-soluble aromatic sulfonate salt with significant industrial utility. Its core value lies in its powerful dispersing, leveling, and complexing properties, making it a critical intermediate and performance additive in advanced manufacturing processes. This compound is essential for industries requiring precise control over particle suspension, dye migration, and scale inhibition, such as textile production, construction materials, and water treatment formulations.

Application

• Textile Auxiliary: Acts as a high-efficiency dispersant and leveling agent in dyeing processes for synthetic fibers.
• Construction Chemical: Used as a plasticizer and water-reducing agent in high-performance concrete admixtures.
• Industrial Cleaning: Serves as a key component in formulated cleaners and degreasers for its surfactant and sequestration properties.
• Water Treatment: Functions as an anti-scalant and dispersant in cooling water and boiler feed water systems.
• Agricultural Formulations: Employed as a wetting and dispersing agent in pesticides and herbicides to improve efficacy.
• Paper & Pulp Industry: Utilized in process chemicals to control pitch and improve pulp bleaching efficiency.
• Chemical Synthesis: A vital intermediate for producing more complex dyes, optical brighteners, and specialty surfactants.

Quality Control

Our Trisodium Naphthalene-1,3,7-Trisulphonate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance, meeting the specifications required for industrial and specialty chemical applications. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is provided with each shipment and is available upon request.

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 after initial use to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
