Name them, then google name+MSDS. Or use find chemicals link on the left. SMILES can be handy (pretty basic SMILES looking at your compounds, I think first will be C#CC=O).

Do you not have the use of a chemical catalogue? Aldrich, Fluka, Alfa Aesar etc...

Or you could use the Merck Index. In addition, the sigma aldrich website will let you search by formula and you can bring up the SDS's.
