Description

8-Hydroxynaphthalene-1,3,6-Trisulphonic Acid, Potassium Sodium Salt is a high-purity, water-soluble organic intermediate and dye precursor. This compound is valued for its ability to introduce sulfonic acid groups and chelating properties into complex molecules, facilitating the synthesis of specialized colorants and functional materials. It is a critical raw material for manufacturers in the dyestuff, pigment, and specialty chemical industries seeking to develop products with enhanced solubility, brightness, and metal-complexing characteristics.

Application

• Primary Intermediate for Dyes and Pigments: Serves as a key building block in the synthesis of acid dyes, direct dyes, and reactive dyes, particularly for textiles like wool, silk, and nylon.
• Metal Complex Dye Production: Used in the manufacture of pre-metallized dyes, where its structure acts as a ligand to form stable complexes with metals such as chromium and cobalt.
• Functional Chemical Synthesis: Employed as an intermediate for creating optical brightening agents (OBAs) and fluorescent whitening agents used in paper, detergents, and plastics.
• Analytical Reagent: Functions as a chelating agent in certain analytical chemistry applications for the detection and quantification of metal ions.
• Research & Development: Utilized in academic and industrial R&D for exploring new organic syntheses, photochemical properties, and advanced material applications.

Quality Control

Our 8-Hydroxynaphthalene-1,3,6-Trisulphonic Acid, Potassium Sodium Salt is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for dye intermediate applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request to support your quality assurance and regulatory needs.

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 sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
