Today, we introduce the high-quality trimethylammonium sulfur trioxide copolymer produced by Shijiazhuang Feizi Chemical Technology Co., Ltd. (hereinafter referred to as "Feizi Chemical"), a company focusing on pharmaceutical intermediates and fine chemicals. With a high purity standard of 99% and stable performance, this product has quickly attracted widespread attention from industries such as pharmaceuticals, new materials, and organic synthesis, providing high-quality raw material support for process upgrading in related fields.

As a key intermediate in organic synthesis and pharmaceutical R&D, Sulfur trioxide trimethylamine complex (CAS No.: 3162-58-1) boasts irreplaceable application value. According to the R&D director of Feizi Chemical, the product appears as a white powder under normal temperature and pressure, with a molecular formula of C₃H₉NO₃S and a molecular weight of 139.17, and its melting point can reach 240℃, featuring excellent thermal stability and chemical activity. It can not only be used as a pharmaceutical intermediate in the synthesis of antihistamine drugs but also serve as a co-catalyst in the production of fine chemicals such as m-chlorobenzoyl chloride, significantly improving reaction selectivity and yield—the selectivity of target products in related processes can reach around 90%.

In the field of new energy material R&D, the innovative application of this product has shown broad prospects. Studies have indicated that using trimethylammonium Sulfur trioxide trimethylamine complex as a sulfur source, ZnSN-C series oxygen reduction reaction catalysts can be prepared via chemical vapor deposition. These catalysts exhibit good electrochemical performance in both alkaline and acidic media, providing a new path for the low-cost industrialization of clean energy devices such as fuel cells. In addition, its strong acidity and high charge density characteristics endow it with practical value in fields like ion exchange resins, water treatment, and metal recovery.

Feizi Chemical’s ability to rapidly industrialize this product stems from its complete production and R&D system. It is understood that founded in 2022, Feizi Chemical has built a 50-mu production base in Shijiazhuang Circular Chemical Industry Park, with a staff of over 50 people, and established a professional R&D center in Zhitong Pharmaceutical Valley of High-tech Development Zone, focusing on new product development and high-end customization services. The company’s management team comes from the core layer of listed pharmaceutical enterprises, and it strictly complies with the ISO9001 quality management system. Meanwhile, it has established long-term cooperation with universities such as Hebei University of Science and Technology and Hebei University of Technology, providing solid technical support for product quality.

"High quality, professionalism, innovation, and integrity are our core business philosophy," said the general manager of Feizi Chemical. The newly launched trimethylammonium Sulfur trioxide trimethylamine complex is produced in strict accordance with quality standards, and flexible packaging solutions can be provided according to customer needs. At present, the product has passed a number of quality tests; in addition to supplying the domestic market, it will also be exported to Europe, America, Japan, Southeast Asia and other regions relying on the company’s mature foreign trade channels.

With the rapid development of green chemical industry and new material industry, the market demand for trimethylammonium sulfur trioxide copolymer is continuously growing. The launch of this new product by Feizi Chemical not only enriches its own product portfolio but also provides the possibility for downstream industries to reduce costs and increase efficiency with its high cost-performance advantage. In the future, the company will continue to focus on technological innovation in the fine chemical field, promote more high-quality chemical products to the market, and inject momentum into the high-quality development of the industry.
