Possible uses
Source: 
This substance has persistent, bioackumulative and toxic properties.This substance is structurally similar to the chemical PFOS, which is a recognised POP under the Stockholm convention. PFDS has been found in human plasma, in birds and fish. It is highly persistent and has the potential for long-range transport. It is expected to be at least as toxic and bioackumulative as PFOS.
