Tetraethyllead (TEL) is an organolead compound historically used as an anti-knock agent in gasoline. It is a colorless to pale yellow liquid with a sweet odor and is highly toxic. TEL has a molecular formula of C8H20Pb and a relatively low boiling point, making it volatile. Its density is significantly higher than that of water, and it is insoluble in water but soluble in organic solvents. The compound is known for its ability to enhance the octane rating of fuels, which helped improve engine performance. However, due to its severe environmental and health impacts, including neurotoxicity and potential to cause lead poisoning, the use of tetraethyllead has been largely phased out in many countries since the late 20th century. Its production and use are now heavily regulated, and alternatives have been developed to replace it in fuel formulations. Safety precautions are essential when handling TEL due to its hazardous nature, and it is classified as a persistent environmental pollutant.
