Merck Acquires Grzybowski Scientific Inventions to Expand Chemical Synthesis Offering

• Revolutionary computer-aided retro-synthesis software optimizes productivity, organic synthesis
• Complements Merck’s leading e-commerce platform and chemistry portfolio of more than 400,000 building blocks, catalysts and reagents for chemical synthesis

Darmstadt, Germany, May 9, 2017 — Merck, a leading science and technology company, today announced the acquisition of Grzybowski Scientific Inventions (GSI), a company that developed the revolutionary computer-aided retro-synthesis tool, Chematica. Chematica uses advanced reaction rules and proprietary algorithms to identify synthesis pathways that meet user-defined constraints. Financial details of the transaction were not disclosed.

“With a 350-year legacy in the pharmaceutical and chemistry business, we recognize the attractiveness of the chemical synthesis and cheminformatics market and how it complements our existing leadership position in chemicals and reagents,” said Udit Batra, Member of the Merck Executive Board and CEO, Life Science.

Virtual synthesis significantly reduces the time between chemical target conception and route evaluation by using a lab’s preferences to filter millions of data points. The tool quickly and efficiently provides optimized routes, providing significant benefit to all researchers, especially those working in medicinal chemistry and drug discovery.

GSI’s knowledge base of tens of thousands of expert-defined rules of chemical reactivity, combined with proprietary algorithms, enables the program to scrutinize millions of synthetic pathways and to choose the routes that lead to desired targets in the most cost-effective way.

“As chemists who grew up with Sigma-Aldrich and Millipore in the lab, we couldn’t be more proud to be acquired by a company with such a long legacy and sincere interest in chemistry,” said Bartosz Grzybowski, founder of GSI and inventor of Chematica. “Combining our revolutionary planning tool with Merck’s large number of available starting materials, and its industry leading e-commerce platform, will provide immense value to our customers.”

The Chematica tool is available now through a limited release for users in academia and in industry.
