Acetone can be used for various different purposes. It's chiefly used as a solvent, meaning it can be used to extract other substances from material and dissolve them.  It can also be used for cosmetic purposes, such as removing nail polish, and for cleaning purposes. There are many other applications for acetone, such as refining gasoline or cleaning laboratory glassware. In addition, it has some medical uses, such as treating some skin conditions. Acetone is also sometimes used as an ingredient in certain household products, such as some types of paint or varnish. Therefore, someone may buy a gallon of acetone for any of the aforementioned purposes. They may not be making drugs, but the purchaser might have a legitimate purpose for doing so.
