About Us

Shanghai Wish Pharma Co., Ltd. was founded in 2016 in the Shanghai Nanhui International Student Entrepreneurship Park. In August 2020, to meet the needs of our expanding business, we relocated to Room 304-C, Building 11, Shanghai Qiyate Center, No. 999 Jiangyue Road, Minhang District, where we established our R&D and pilot testing center.

As a high-tech enterprise, we specialize in the process development and scale-up production of challenging fine chemicals. Our laboratory has successfully passed the environmental impact assessment and acceptance procedures in Shanghai, ensuring compliance and sustainability.

The facility is equipped with state-of-the-art instruments, including multiple Agilent gas chromatographs, Waters liquid chromatographs, a Karl Fischer moisture analyzer, digital melting point analyzer, and other precision analytical tools. In addition, our 50–100 L pilot-scale reactors enable efficient small-batch production and process optimization.

Beyond our Shanghai R&D base, we operate a 76-acre production facility in Meizhou, Guangdong, dedicated to large-scale manufacturing.

Our core business encompasses the R&D, production, and sales of active pharmaceutical ingredients (APIs), intermediates, food additives, and other structurally defined compounds. The Shanghai laboratory focuses on kilogram-scale synthesis, while the Meizhou plant supports industrial-scale production.

We possess strong expertise in anhydrous and anaerobic reactions (including butyllithium, formate, and lithium aluminum hydride reactions), epoxidation, bromination, reductive amination of olefins, oxidation and reduction reactions, and the synthesis of pinacol boronic esters and boronic acids. Our team has extensive experience in scaling up processes from hundreds of kilograms to multi-ton levels, ensuring reliability and consistency from laboratory to full-scale production.
