eMolecules is a search engine for chemical molecules. The system was founded by scientists for scientists in 2005 with one goal in mind: reduce drug discovery timelines through improved efficiencies. After spending 25 years in drug discovery, eMolecules took a step back and looked at every step of compound sourcing, procurement and logistics and developed tools and standards to streamline the overwhelming process. 9 of the 10 largest pharmaceutical companies and 4 of the 5 largest biotechs work with eMolecules.

eMolecules works with 150 trusted suppliers in order to provide customers with a variety of options and services.
