Poly(difluoromethylene), α-[2-[(2-carboxyethyl)thio]ethyl]-ω-fluoro-, lithium salt

Made for specialty coatings, inks/paints, metal finishing, and some firefighting foams; can reach air, dust, and wastewater during manufacture or use [1][2].

Drinking water near industrial sites or firefighting areas, household dust and treated products, certain foods, and on-the-job contact in facilities using PFAS [1][2][3].

PFAS don’t break down easily; some build up in people and are associated with immune effects, higher cholesterol, liver and developmental effects. PFOA (a PFAS) is classified carcinogenic to humans [1][3][4][5]. Data for this specific PFAS are limited; concerns come from the PFAS class.

Workers handling PFAS, people using private wells near industry or airports/bases, pregnant people and infants, and firefighters [1][2][3].

Check local water reports; consider NSF/ANSI 53 or 58 certified filters (activated carbon or reverse osmosis) for PFAS; reduce use of stain‑ or water‑resistant treatments; wet‑clean dust; follow workplace PPE/hygiene; heed local advisories [2][3][6].
