1-Pentanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,5-undecafluoro-, compd. with 2,2'-iminobis[ethanol] (1:1)

Manufacturing and use as a surfactant in metal plating, firefighting foams, and coatings; releases can occur to wastewater and air during use and disposal [1][2].

Drinking water near industrial sites or airports, workplace air/mist and skin contact, and smaller amounts from food and household dust [1][3].

PFAS are very persistent; exposure has been linked to reduced vaccine response, higher cholesterol, liver and thyroid changes, and developmental effects. Some PFAS (e.g., PFOA) cause cancer. Data for this exact PFAS are limited, so agencies advise minimizing exposure [1][2][4].

Workers in plating, firefighting, and fluorochemical manufacturing; people using private wells near sources; pregnant people and infants [1][3].

Check local water results; test private wells; use certified filters (reverse osmosis or activated carbon); follow workplace controls/PPE; reduce use of stain- or water-repellent products [2][3][5].
