Usage of Sodium 2,3-dihydroxynaphthalene-6-sulfonate
1. Photographic & Diazo Materials (Core Application)
Sodium 2,3-dihydroxynaphthalene-6-sulfonate is widely used as a coupling agent (coupler) in the production of diazo photosensitive paper (blueprint paper / diazo copy paper). It reacts with diazonium salts during the imaging process to produce stable, clear color prints, making it essential for the traditional blueprinting process in engineering and design industries.
2. Dye Intermediate
A key raw material for synthesizing acid dyes, reactive dyes, and functional azo dyes. It improves the color strength, lightfastness, and washfastness of the final dyestuffs, and is used in the production of dyes for textiles, inks, and pigments.
3. Organic Synthesis & Analytical Chemistry
• Serves as a building block/intermediate in organic synthesis for producing fine chemicals and other naphthalene-based derivatives.
• Used as a reagent in colorimetric analysis and analytical chemistry, including applications in boron-specific adsorbents for water treatment research.
Short Commercial Version (for product listings)
Sodium 2,3-Dihydroxynaphthalene-6-sulfonate is a key chemical intermediate primarily used as a coupling agent for diazo photosensitive paper and as a raw material for manufacturing acid and reactive dyes.
