Shanghai Yaokan Chemical Co., Ltd., established in 2018, is a comprehensive high-tech enterprise integrating R&D, production, and sales of chromatographic solvent products with over a decade of experience in ultra-clean, high-purity reagent manufacturing. The company specializes in providing high-purity reagents for laboratory analysis and the pharmaceutical manufacturing industry. With significant investment in its Daqing production base in Northeast China, and building on world-class T2P2 high-purity reagent manufacturing technology, the company has developed its own proprietary production processes for high-purity chromatographic acetonitrile, methanol, and other high-purity reagents. It has established China's first advanced ultra-clean, high-purity production line with independent intellectual property rights, including a 5,000 tons/year preparative-grade acetonitrile unit, 2,000 tons/year anhydrous and anhydrous bio-grade acetonitrile unit, 2,000 tons/year high-performance liquid chromatography (HPLC) high-purity solvents (acetonitrile, methanol, n-hexane, etc.), and 1,000 tons/year ultra-dry high-purity solvents, with a total annual capacity of 10,000 tons. It is the enterprise in Northeast China with the most comprehensive product range, largest production capacity, and most advanced technology. It has become a high-end chemical reagent R&D and production base in northern China, integrating R&D platforms, experimental bases, and scientific and technological achievement transformation services. It holds a leading position in the domestic production of ultra-clean, high-purity reagents and is a national high-tech enterprise.

The company consistently adheres to the business philosophy of "market-oriented, quality-based, management-carried, and benefit-driven," providing ultra-clean, high-purity solvents and reagent products that satisfy customers. Its products are widely used in biopharmaceuticals, nucleic acid drugs (oligonucleotides), peptide drug preparation (semaglutide, tirzepatide), chromatographic analysis, food testing, pesticide residue testing, and other industries. The company actively explores overseas markets, having established an international sales team, and its high-purity products are exported to countries such as those in Europe, the United States, and Singapore. In addition to producing pharmaceutical, chemical, or analytical-grade reagents and solvents, the company also offers specialized product lines, including formulations and ultra-pure solvents for custom applications, and is ready to create tailored projects for clients to assess feasibility and cost. Leveraging the integrated advantages of "technological breakthrough-industrial upgrade-digital transformation," and using raw materials such as methanol, acetonitrile, ethanol, sulfuric acid, and nitric acid, the company enhances its independent R&D capabilities to produce high-end products under its own brand Y&F (high purity solvents), including ultra-clean, high-purity reagents, electronic chemicals, and pharmaceutical excipients. Shanghai Yaokan will continue to deepen product quality, improve service efficiency, and commit to creating greater value for every partner, collectively writing a new chapter in the field of high-purity reagents.
