Perfluorodecanesulfonic acid is a persistent organic pollutant, known for its strong resistance to degradation.[5]

Occurrence

Perfluorodecanesulfonic acid is a micropollutant found in marine organisms and sewage sludge.[6]

Physical properties

Perfluorodecanesulfonic acid forms a dark brown to black solid.[7]

Use

Perfluorodecanesulfonic acid, as a very strong acid, can be used as a catalyst for regioselective alkylations and organic synthesis.[8][9]
