A popular weak acid is biphenyl methanol, which gives a deeply colored dilithio derivative at the end point. Chorus systems are reliable water purification units constructed from the highest quality components. Suppliers found in search results. Also, it is broadly employed as a strong base superbase in the synthesis of organic compounds as in the pharmaceutical industry. Size: 1mole. Furthermore, in addition to being a strong nucleophile, n-BuLi binds to aprotic Lewis bases, such as ethers and tertiary amineswhich partially disaggregate the clusters by binding to the lithium centers. Size: 0.
Butyllithium C4H9Li PubChem
Aldrich; n-Butyllithium solution M in hexanes; CAS No.: M in hexanes. Synonym: n-BuLi, Butyl lithium, Butyllithium solution, Lithiumbutanide. This product line ranges from Brønsted and Lewis acids, Chemfiles. n-Butyllithium (abbreviated n-BuLi) is an organolithium reagent. It is widely used as a n-BuLi exists as a cluster both in the solid state and in a solution. of n-BuLi, the clusters are tetrameric (in ether) or hexameric (in cyclohexane).
Reflecting its "electron-deficient character," n-butyllithium is highly reactive toward Lewis.
