CAS 68084-62-8

2-Propenoic acid, 2- [methyl[(pentadecafluoroheptyl)sulfonyl]amino]ethyl ester

This fluorinated acrylate is a PFAS-related chemical used to make water- and stain‑repellent coatings for textiles, paper, and other materials. It matters because PFAS are extremely persistent; PFAS coatings and precursors like this can transform into other long‑lasting PFAS in the environment [1][2].

Where It Comes From

Made for surface‑treatment polymers and coatings; released during manufacturing, product use (washing/wear), and disposal [2][3].

How You Are Exposed

Drinking water near production or contaminated sites, indoor dust from treated carpets/upholstery, food contact papers, and workplace air/skin contact in finishing/coating jobs [1][2][4].

Why It Matters

PFAS persist and can build up in people; exposure is linked to reduced vaccine response, increased cholesterol, liver and thyroid changes, and some PFAS (e.g., PFOA) are linked to cancer [1][5][6].

Who Is at Risk

Workers in fluorochemical and textile treatment facilities; people using private wells near PFAS sources; pregnant people, infants, and children [1][2].

How to Lower Your Exposure

Treat drinking water with effective filtration (granular activated carbon, reverse osmosis, or ion exchange) where needed; choose PFAS‑free or “no stain‑resistant treatment” products; wet‑dust and use a HEPA vacuum; follow local fish/water advisories; test private wells near potential sources [2][7][8].
