Poly(oxy-1,2-ethanediyl), α-[2-[ethyl[(pentadecafluoroheptyl)sulfonyl]amino]ethyl]-ω-methoxy-

Made for specialty coatings, textiles, paper, inks/paints, and industrial wetting/leveling agents; PFAS precursors like this can transform into more persistent PFAS in the environment [1][3].

Drinking water near manufacturing or use sites, indoor dust from treated products, some foods, and workplaces that make or use PFAS [1][2][3].

Data on this exact compound are limited; PFAS as a class are linked to higher cholesterol, immune effects (reduced vaccine response), liver enzyme changes, and developmental effects; some (e.g., PFOA) cause cancer [1][4][5].

Workers handling PFAS, communities with contaminated water, pregnant people and infants, and people who eat contaminated fish [1][2].

Check local water reports; consider certified filters (activated carbon or reverse osmosis), follow fish advisories, reduce indoor dust with wet cleaning, and avoid optional stain/water‑repellent treatments when possible [1][2].
