A type of chemical compound that is made from phenol and contains nitrogen and oxygen; it is known for being toxic and is used in some pesticides.
Dinitrophenol is often used in laboratories for various chemical reactions.
Dinitrophenol is formed from "di-" (meaning two), "nitro" (from Latin "nitrum", meaning saltpeter or nitrate), and "phenol" (from Greek "phaino", meaning to show or appear, and "ol", a suffix used in chemistry to denote alcohols or phenolic compounds). The term refers to a chemical compound that contains two nitro groups attached to a phenol structure.
Think of 'two' ('di-') nitro groups being attached to a 'phenol' structure, which helps you remember that dinitrophenol is a compound with two nitro groups.
