Molecular Pathway Generator

Our IUPAC nomenclature tool features on-the-fly, stereochemistry complete naming updated as you design your molecule.

To view more detailed information about the molecule you've created, please clickhere to see the molecule with our full-featured design tool.

Advanced design tool includes

Detailed information about each atom in your molecule including hybridization and number of free electrons
Display of overall molecule properties including aromaticity
A link to your molecule so you can share the molecule you have created with others. Also a link to search Google and PubChem for your molecule
Alternative view modes of your molecule including showing all Hydrogen atoms and viewing a ball-stick model
An option to turn off stereochemistry nomenclature

Our IUPAC name parsing feature allows you to view and interact with the molecule itself simply by entering the systematic or common IUPAC name of the molecule. You can enter the name with or without stereochemistry.

If your name isn't quite correct, it will also try to guess what you meant. For example, if you enter the molecule name "propanone", it will guess that you meant a propane chain with a ketone functional group located on the first carbon, and show you the propanal molecule with an aldehyde group instead.

Try it out! If you're feeling adventurous, you can also try entering abbreviations for molecules, including the 1 and 3 letter amino acid abbrevations.

Also feel free to view your molecule with our full-featured design tool.

Our reaction simulator tool anticipates the product of a specific reaction applied to a given starting reactant molecule.

Rules are used to predict the product based on functional groups present and other properties of the reactant molecule, rather than just the specific IUPAC name of the molecule. For example, the chlorination of an alkene reaction will replace the double bond of two alkene carbons with a chlorine atom attached to each carbon. The power of modeling reactions with rules in this manner is that the rules can be extended to a wide variety of molecules. Not only can we anticipate that propene will be chlorinated to 1,2-dichloropropane, but more generally we can anticipate that a molecule <chain name>ene will be chlorinated to 1,2-dichloro<chain name>ane.

Our pathway search tool allows you to enter a given starting reactant and product molecule and search for a synthesis pathway between the two.

Options can be selected for finding a variety of the most optimal synthesis pathways, including

Fewest number of steps
Lowest cost
Shortest reaction time

You can control the sources our tool will utilize in searching for the optimal pathway, including

Our modeling of reactions by generic rules
Known reaction database by given molecule IUPAC names
The external Rhea Database source of reactions

You can also use our Smart Search feature to aid in your synthesis pathway search. The Smart Search uses a heuristic calculation to guide its pathway search from the origin molecule to the goal molecule.
