1-Amino-8-Hydroxynaphthalene-3,6-Disulphonic Acid 99% Purity CAS 90-20-0 for Az Dye Manufacturing

Product Specifications

Unstable Az Dye Intermediates Disrupt Production? 1-Amino-8-Hydroxynaphthalene-3,6-Disulphonic Acid (CAS 90-20-0) With 99% Purity Ensures Consistency

We’ve witnessed countless dye manufacturers struggle with batch-to-batch variations in 1-Amino-8-Hydroxynaphthalene-3,6-Disulphonic Acid purity—fluctuations as small as 2% can cause significant color偏差 and increase wastewater treatment costs. Delayed deliveries of this critical intermediate have forced production lines to halt, while inconsistent solubility has led to uneven dyeing and product rejects. In our 10+ years serving global chemical enterprises, these are the recurring challenges that erode profitability in azo dye manufacturing.

A Stable and Reliable Chemical Supply Solution for Dye Manufacturers

Our 1-Amino-8-Hydroxynaphthalene-3,6-Disulphonic Acid addresses these pain points through a combination of stringent quality control and supply chain resilience. With a dedicated production capacity of 20t/year and strategic warehousing, we ensure consistent availability—from kilogram-scale R&D trials to ton-level mass production. This high purity az dye intermediate integrates seamlessly into industrial processes, minimizing reaction variables and supporting stable dye synthesis for coating, textile, and plastic coloring applications.

Typical Industrial Applications

As an important intermediate in the manufacture of azo dyes, this compound serves as a critical building block in producing a wide range of colorants for industrial coatings, plastic additives, and textile dyes. Its chemical structure enables precise coupling reactions, making it indispensable in the synthesis of azo compounds with specific chromatic properties. All applications are strictly limited to industrial manufacturing processes, with no use in consumer products or direct human contact scenarios.

Why Key Specifications Matter for Dye Production

The >99% purity of our 1-Amino-8-Hydroxynaphthalene-3,6-Disulphonic Acid directly translates to fewer副反应 and lower impurity loads in downstream azo dye synthesis, reducing purification steps and waste treatment costs. Its solid state ensures stable handling and metering, while the defined melting point (>300°C) guarantees thermal stability during high-temperature reaction processes. The standardized packaging options (25kg bags, 250kg drums, 1250kg IBCs) facilitate accurate dosing and minimize material loss, critical factors in maintaining consistent dye quality across production batches.
