We consulted the APA Style experts at http://apastyle.org, who replied as follows:
This situation follows the pattern for a work in a database, meaning you give database URL or name (I went with URL). There is no author, so the title (Acetone) moves to the author position. I used the year of the last complete update for the year.
Acetone. (2015). Retrieved March 8, 2016, from http://toxnet.nlm.nih.gov/cgi-
In text: (“Acetone,” 2015).
The retrieval date is included because TOXNET updates their content so you would want to state when you retrieved the work.
