Description

Disodium 4,5-Bis(Isopropyl)Naphthalene-1,8-Disulphonate is a high-purity, water-soluble anionic surfactant and dye intermediate. This compound is valued for its excellent wetting, dispersing, and solubilizing properties in aqueous systems. It serves as a critical functional additive and chemical building block for manufacturers in the textile, agrochemical, and specialty chemical industries.

Application

• Textile Processing: Acts as a high-efficiency dispersing and leveling agent in dye baths, particularly for synthetic fibers.
• Agrochemical Formulations: Used as a wetting and dispersing agent in the production of wettable powders (WP), suspension concentrates (SC), and other pesticide formulations.
• Dye and Pigment Intermediate: Serves as a key sulfonated intermediate in the synthesis of acid dyes, reactive dyes, and organic pigments.
• Industrial Cleaning: Functions as a surfactant in specialized industrial and institutional cleaning products.
• Paper and Pulp Industry: Employed as a dispersant for coatings and in certain pulping processes.
• Construction Chemicals: Can be used as a plasticizer or water-reducing agent in specific concrete admixture formulations.

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.
