Butyllithium Chemical

CAS No         109-72-8

Application / Uses Preparation
n-Butyllithium is an organolithium reagent. It is widely used as a polymerization initiator in the production of elastomers such as polybutadiene or styrene-butadiene-styrene (SBS). Also, it is broadly employed as a strong base (superbase) in organic synthesis, both industrially and in the laboratory.

CAS No         598-30-1

Application / Uses Preparation
Sec-butyllithium is an organometallic compound with the formula CH3CHLiCH2CH3, abbreviated sec-BuLi or s-BuLi. This chiral organolithium reagent is used as a source of sec-butyl carbanion in organic synthesis

CAS No        594-19-4

Application / Uses Preparation
Tert-butyllithium is a chemical compound with the formula (CH3)3CLi. As an organometallic compound, it has applications in organic synthesis (see also grignard reaction) since it is a sufficiently strong base to deprotonate many carbon acids, including benzene. In regard to molecular aggregation state, the compound exists in clusters.
