Designing new chemicals possessing a set of desired physical properties is one Synapse's key capabilities. Synapse enables you to design chemicals both graphically and combinatorially. The functions, constraints, groups and constraints needed to design chemicals, as well as the generated candidates, are stored in Chemical Design Documents.

• Using a Combinatorial Design to assemble multiple occurrences of the groups:
  -CH₃

  -CH₂-

  >CH-

  >CH<

  =CH-

  =CH<

  -F
  into molecular structures that satisfy constraints on vapor pressures, heat capacities and thermal conductivities.
• Using a Graphical Design to examine how different subsituents change the physical properties of morpholine. The graphical design enables you guide the search using your knowledge of what substituents can be readily synthesized.

A Chemical Design Document contains five chapters. Each of these chapters can be accessed by clicking on its corresponding tab in the document's Tab Pane.
