Mathematica 8's curated ChemicalData contains close to 44,000 different listings. This Demonstration lets you drill down to any of these chemicals via chemical class designations (Solid, Acid, Chiral, etc.). Once a class is selected, a chemical can be selected. Several views of the molecule can be chosen, as well as Physical, Thermal, Structure, and Shipment data accessed via various flip views. A Tooltip is included to show information such as alternate names and NFPA placards, selected via buttons in the Tooltip cell; followed by mousing over the chemical's molecular formula. Detailed operation guidance via tooltips associated with text throughout the Demonstration can be turned on or off via the checkbox.
