The company has established R&D centers in Nanjing and Taizhou, with nearly 50 chemists dedicated to developing innovative technologies. Its manufacturing sites for intermediates and APIs are located in Hubei and Gansu provinces, and have been approved by main regulatory authorities home and abroad. We own the core technology advantages in the area of bromination, enzyme/metal-catalyzed, nitration and hydrogenation, and obtain multiple patents for invention. We stick to raising the value both for the company and customers, and strive for creating more valuable product for the health of the life as our mission.
