sec-Butyllithium, 12% in Cyclohexane

CAS No. 598-30-1

QS-PDS-037 Revision: 03

Date of Last Revision: November 7, 2022

Formula: CH3CH2CH2CH2-Li
Appearance: Clear to yellow solution
Application: sec-Butyllithium is a very strong base, exceedingly useful inorganic synthesis. SBL has found particular utility in the ortho
metallation of aromatic substrates. SBL is also a very effective
initiator of anionic polymerization of styrene and conjugateddienes. The synthesis of solution SBR and of styrenic
thermoplastic elastomers (TPEs), in particular, is facilitated bySBL. References: The Chemistry of Organolithium
