perfluoroheptanoic

Perfluoroheptanoic acid, often abbreviated as PFHpA, is a synthetic perfluorinated carboxylic acid. It belongs to the broader class of per- and polyfluoroalkyl substances (PFAS), which are characterized by a chain of carbon atoms where hydrogen atoms have been replaced by fluorine atoms. PFHpA has the chemical formula C7F14O2. It is a strong acid due to the electron-withdrawing nature of the fluorine atoms.

This compound is a non-polymeric substance that is manufactured. It is persistent in the environment, meaning it does not readily break down. PFHpA has been detected in various environmental compartments, including water, soil, and air, as well as in wildlife and human blood. Its persistence and widespread presence are characteristic of many PFAS compounds.

Perfluoroheptanoic acid has been used in some industrial applications, although specific uses can be proprietary. Like other PFAS, it may have been utilized for its surfactant properties, contributing to water and oil repellency. Concerns regarding the environmental and health impacts of PFAS have led to increased scrutiny and regulatory efforts worldwide. Research continues to investigate the sources, fate, and potential effects of PFHpA and other perfluorinated compounds.
