ChemicalSearch: Find Chemicals by Various Criteria
Find a chemical by basic criteria like molecular weight and predicted logP, or by the more abstract notion of structural similarity.
 
Virtual Chemical Space: Retro-Synthesis and Combinatorial Library Design
Interactively deconstruct target compounds into component precursors and reconstruct similar building-blocks into combinatorial libraries representing the "virtual chemical space" near the target compound.
 
Reaction Explorer: Synthesis Explorer and Mechanism Explorer
Interactive system for learning and practicing reactions, syntheses and mechanisms in organic chemistry, with advanced support for the automatic generation of random problems, curved-arrow mechanism diagrams, and inquiry-based learning.
 
Datasets: For Machine Learning and Searching Experiments
Various available chemical datasets annotated with interesting properties to train and test machine-learning prediction and searching methods.
 
Supplements: Articles and Support Material
Online articles relating to the system with supplementary data and figures referenced in them.
