This invention provides a composition that contains PFOB with a PFOA content lower than that of known PFOB, and that is less likely to have an adverse effect on the environment; and provides a method for producing PFOB. The composition contains C.sub.8F.sub.17Brand further contains C.sub.7F.sub.15COOH, wherein C.sub.7F.sub.15COOH is present in a concentration of 25 ppb or less based on the total weight of C.sub.8F.sub.17Br. The method for producing C.sub.8F.sub.17Br comprises reacting C.sub.8F.sub.17I and a brominating agent to obtain C.sub.8F.sub.17Br, and alkali-washing the obtained C.sub.8F.sub.17Br to reduce the C.sub.7F.sub.15COOH content to 25 ppb or less based on the total weight of C.sub.8F.sub.17Br.
