perfluorotetradecanoic acid [Supplementary Concept]
Date introduced: November 23, 2021
Organic Chemicals
A broad class of substances containing carbon and its derivatives. Many of these chemicals will frequently contain hydrogen with or without oxygen, nitrogen, sulfur, phosphorus, and other elements. They exist in either carbon chain or carbon ring form.
Year introduced: 1998
Hydrocarbons, Halogenated
Hydrocarbon compounds with one or more HYDROGEN atoms substituted with HALOGENS.
Year introduced: 1966
Hydrocarbons, Fluorinated
Inert liquid or gaseous halocarbon compounds in which FLUORINE replaces some or all HYDROGEN atoms.
Year introduced: 1974
Hydrocarbons
Organic compounds that primarily contain carbon and hydrogen atoms with the carbon atoms forming a linear or circular structure.
Fluorocarbons
Liquid perfluorinated carbon compounds which may or may not contain a hetero atom such as nitrogen, oxygen or sulfur, but do not contain another halogen or hydrogen atom. This concept includes fluorocarbon emulsions, and fluorocarbon blood substitutes. Perfluorinated and related polyfluorinated chemicals are referred to as PFAS and are defined as chemicals with at least two adjacent carbon atoms, where one carbon is fully fluorinated and the other is at least partially fluorinated.
Year introduced: 1977(1975)
