Try looking in the MiKTeX package manager list, you'll immediately find 4
chemistry related packages. Or if you open the MiKTeX Options wizard and
look on the Packages tab under Applications - Chemistry, you'll find 5
chemistry related packages.

Looking at the CTAN entry for ppchtex (where did you get it from?), it
appears to be part of the Context package and probably needs some parts of
the full setup.
