Description

Application

sec-Butyllithium solution (1.4M in cyclohexane) has been used in the multi-step synthesis of 5-methyl-5,6-dihydrothymidine (5-MDHT) from thymidine. It has also been used in the copper-catalyzed asymmetric allylic alkylation (AAA) of allyl bromides, chlorides, and ethers in the presence of a chiral ligand.

Packaging

The 25 mL Sure/Seal^™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
