The database is populated with target chemicals, corresponding listings of reagent chemicals, corresponding listings of equipment and corresponding listings of procedures. The database is then searched in response to user identification of a target chemical. In response, a listing is displayed of reagent chemicals that are used to synthesize the target chemical, equipment that is used to synthesize the target chemical, and a procedure that is used to synthesize the target chemical by reacting the reagent chemicals in the equipment according to the procedure. An icon-based reaction editor and/or context-sensitive Boolean query option generators may be provided. A reaction template may be used to perform predictive chemistry. A reaction relay may be used to graphically display related chemicals and procedures using a hub and spoke arrangement.
