Chemistry 343

This is an extremely useful database for synthetic chemists. It contains monographs on thousands of reagents used in synthesis. If you have to use a reagent that you have never used before, find it in this database: you will find a nice monograph describing its reactivity, and details about its stability, its purification, about how you should handle it (is it poisonous? is it air stable? is it stable at room temperature?), etc.
