CAS 335-67-1

Chemical Name: Perfluorooctanoic acid (PFOA)

Molecular Formula:C₈HF₁₅O₂

Molecular Weight: 414.07 g/mol

Physical Form:
White solid or wax-like solid; highly chemically and thermally stable; insoluble in water but soluble in certain organic solvents.

Applications:

  • Used as a surfactant and emulsifier, especially in the production of fluoropolymers such as PTFE

  • Previously applied in metal plating, non-stick coatings, and various industrial surface treatments

  • Now heavily restricted or phased out worldwide due to environmental persistence and health concerns, with safer PFOA-free alternatives used instead
