PubChem Structure Search

PubChem Structure Search allows the PubChem Compound Database to be queried by chemical structure or chemical structure pattern. 


Please see the Structure Search Help Document for more information.


The redesigned PubChem Search provides an easier access to chemical information in PubChem with enhanced search abilities. The  mobile-friendly, responsive interface works on the device you want to use. It will replace this old service in the future.
