The web has many online databases of properties of compounds locked behind search interfaces, but I can't find anything you can actually download.
I want a corpus of data that might allow me to, say, sort compounds by enthalpy of formation, or melting point, or other properties you'd encounter in a high school chemistry class. I don't need environmental impact properties, or toxicology data, or even molecular structure, and I don't need to know about exotic stuff hardly anyone's ever heard of. Just the basic simple things you would expect to be easily available like just about everything else on the web.
There are handbooks of general properties of compounds. Collections like these are perfect. Surely someone has put information that exists in a book into digital format.
I don't mind paying for it. But I can't even find it.
