Butyllithium

Description:
Butyllithium, with the CAS number 109-72-8, is an organolithium compound widely used in organic synthesis as a strong base and nucleophile. It typically exists as a colorless to yellowish liquid or solid, depending on its form and concentration. Butyllithium is highly reactive, particularly with moisture and air, forming lithium hydroxide and other byproducts, which necessitates careful handling under inert atmospheres. It is known for its ability to deprotonate weak acids and initiate polymerization reactions, making it valuable in the production of various polymers and in the synthesis of complex organic molecules. The compound is also utilized in the preparation of lithium reagents and as a catalyst in certain reactions. Due to its reactivity, butyllithium poses significant safety hazards, including flammability and potential for violent reactions with water or alcohols, thus requiring stringent safety protocols during storage and use. Proper protective equipment and storage in airtight containers are essential to mitigate risks associated with this compound.
