Hints for using these resources:

Try a few of the links above.  Search for acetone for example.  You'll find that
multiple entries will appear.  Make sure that the entry you choose is actually
for the desired compound and not a derivative of that compound.

Entries will appear for "acetone" as well as others, such as "acetoacetone",
"acetylacetone", etc.  These are three different compounds with different
properties.

You will also find different grades of the same compound and different brand
names.  The physical property information from different manufacturers
should be the same.

One final note - Sometimes different isotopes are used in the preparation of
these compounds.  For instance, you may entries for "acetone-D6".  This is
acetone in which the hydrogens have been replaced by deuterium atoms.
"Acetone" and "acetone-D6" are two different chemicals.  Go ahead and
compare the physical properties.
