Congener (chemistry)
From Wikipedia, the free encyclopedia
Example of a congener: the number and locations of Cl groups can vary
In chemistry, congeners are related chemicals, e.g., elements in the same group of the periodic table, or derivatives thereof.[1]
- Congeners refer to the other elements in a group in the periodic table. For example, the congeners of the Group 11 element copper are silver and gold. Similarly, sodium chloride and potassium chloride may be considered congeners.
- Congeners refer to the various oxidation states of a given element in a compound. For example, titanium(II) chloride (titanium dichloride), titanium(III) chloride (titanium trichloride), and titanium(IV) chloride (titanium tetrachloride) may be considered congeners.
- There are 209 congeners of polychlorinated biphenyls (PCB) as well as 209 congeners of polybrominated diphenyl ethers (PBDE).
- Congeners of oleic acids can modify cell membrane behavior protecting against tumors or having effects on blood pressure.
