Perfluorododecanoic acid (BioDeep_00000182249)

描述信息

Perfluorododecanoic acid, also known as tricosafluorododecanoic acid, is an organic compound containing a perfluorinated carbon chain. This compound is a type of fluoroalkanoic acid, specifically a derivative of dodecanoic acid where all the hydrogen atoms attached to the carbon atoms are replaced by fluorine atoms.

A fluoroalkanoic acid that is dodecanoic acid in which all of the hydrogens attached to carbon atoms are replaced by fluorines. It is a highly persistent, bioaccumulative breakdown product of stain- and grease-proof coatings on food packaging, soft furnishings and carpets.
