Sodium Naphthionate / CAS 130-13-2

OVERVIEW

Benefits

1. Robust Production Capacity and Leading Market Status：HENAN SUITONG CHEMICAL Co.,Ltd. has been deeply involved in the fine chemical industry for many years and has developed into one of the few domestic enterprises specializing in rare fine chemicals. The company operates mature, large-scale production lines with a total annual output of 5,400 tons for 1,4-Acid, Nevinic acid, and Rhodamine B, making it a major producer in the industry. Leveraging powerful mass-production capabilities and ample inventory, the company provides a long-term, stable supply for large domestic and foreign trade orders with short lead times, fully meeting the bulk procurement needs of global customers.

2. Exquisite Process R&D and Superior Physico-chemical Properties：The company invests heavily in process R&D and automated equipment upgrades. Following years of optimization, the production process for 1,4-Acid is technologically mature, resulting in high purity.

Physical Properties: The product typically appears as a white or pale yellow crystalline powder. Due to the sodium sulfonate group, it is easily soluble in water and slightly soluble in organic solvents such as ethanol.

Chemical Activity: The amino group can participate in diazotization reactions to generate diazonium salts, which then couple with phenols or aromatic amines to form high-quality azo compounds, such as dyes.

3. Extensive Application Range Covering High-End Research and Industry：As a highly valuable fine chemical intermediate, the application scenarios for 1,4-Acid extend from traditional industry to cutting-edge technology:

Industrial Dyes: It is used to synthesize azo dyes (such as Direct Red and Acid Orange), imparting vibrant colors to textiles.

Environmental Monitoring & Safety: It is widely used for complexing various metal ions (such as Fe, Zn, Cd, and Ni) and is applied in monitoring equipment for toxic chemical leaks and water quality testing.

Life Sciences: It plays a key role in DNA structure probes, molecular optical switches, and clinical medical research.

New Materials: It is suitable for the synthesis of optical devices, information storage components, and thermal/optical switch materials.

4. High Market Share and Excellent International Recognition：Driven by exceptional product quality, Henan Suitong’s core products, including 1,4-Acid, hold a 56% share of the domestic market. Furthermore, the company maintains highly mature foreign trade channels, with exports accounting for over 61% of total output. Products are exported to countries such as India, Pakistan, and Vietnam. This high international market share demonstrates that its products have reached first-class global standards in terms of compliance, quality, and brand reputation.

5. Commitment to Safety and Environmental Protection for Sustainable Supply：The company prioritizes the treatment of "three wastes" (waste gas, water, and residue) before production begins, practicing the philosophy that "lucid waters and lush mountains are invaluable assets". By strictly adhering to standardized and normalized safety management, the company effectively avoids production halts or restrictions caused by environmental or safety risks. This high level of compliant operation provides customers with a long-term, reliable, and sustainable supply guarantee.

6. Innovation-Driven Leadership and Customized Service Response：Acting as a pioneer in technological self-reliance, the company relies on its independent R&D system and professional talent team to continuously improve the autonomy of key technologies. Beyond providing standard specifications of 1,4-Acid, the company offers in-depth support in technical consulting, fine-tuning product specifications, and providing customized application solutions. Through all-around, one-stop service, Henan Suitong achieves win-win growth with its partners.
