About PharmaBlock



PharmaBlock Sciences (Nanjing), Inc. is a leading innovative chemistry products and services provider throughout the pharmaceutical R&D process. Its core businesses include: a catalog of specially designed scaffolds and building blocks; custom synthesis; process development; manufacturing of key intermediates and RSMs; and FTE services. The company was listed on Shenzhen Exchange Stock in China on November 10, 2017.

PharmaBlock has rapidly gained recognition for its outstanding capability in the design, synthesis, and supply of lab scale building blocks. Building on that success, the company acquired Shandong Diai Biotechnology Co., Ltd. as its pilot plant and manufacturing site in 2016, and is providing scale-up synthesis and manufacturing of key intermediates/RSMs. PharmaBlock is now committed to a more comprehensive and long-term service to valued customers.

Since its establishment, PharmaBlock has partnered with over 80% of the top 20 pharmaceutical companies, and hundreds of small to medium-sized biotechs around the world. In 2012, the company opened a facility in the San Francisco Bay Area, and set up the United States headquarters in Pennsylvania in 2018, expanding the inventory, business development and lab functions for more efficient and timely services to local customers in the United States and Europe.
