Example of a congener: the number and locations of Cl groups can vary

In chemistry, congeners are related chemical substances "related to each other by origin, structure, or function".[1]

Common origin and structureEdit

Any significant quantity of a polyhalogenated compound is by default a blend of multiple molecule types because each molecule forms independently, and chlorine and bromine do not strongly select which site(s) they bond to.

Common originEdit

  • Congener (alcohol), substances other than alcohol (desirable or undesirable) also produced during fermentation.
  • Congeners of oleic acids can modify cell membrane behavior, protecting against tumors or having effects on blood pressure.[2]
