Perfluoro(4-ethylcyclohexane)sulfonic acid (PFEtCHxS) is a synthetic perfluorinated alkyl substance that has been used as a surfactant and in various industrial applications.

Chemical properties

PFEtCHxS is a colorless liquid at room temperature and has a high surface tension, making it suitable for use as a surfactant.

The molecule contains two chiral centers.

Applications

PFEtCHxS has been employed in various industrial processes, including: [1]

Its surfactant properties and resistance to extreme conditions make it useful in these applications.

Environmental concerns

Like other perfluorinated compounds, PFEtCHxS is highly persistent in the environment and has been detected in various environmental matrices, including water, soil and biota. There are concerns about its potential bioaccumulation and adverse effects on human health and ecosystems. [2] [3]
