It is crucial in the production of elastomers such as polybutadiene (PBD), styrene-butadiene rubber (SBR), and styrene-isoprene-styrene (SIS) block copolymers.Strong Base in Organic SynthesisAs a powerful base (pKb ≈ -36), n-BuLi is used for deprotonation (metalation) of weakly acidic compounds, forming reactive organolithium intermediates. This property is utilized in the synthesis of complex organic molecules, including phar nnaceutical intermediates and fine chemicals.Halogen-Lithium Exchangen-Butyllithium can undergo halogen-lithium exchange reactions with organic bromides and iodides, generating other organolithium compounds. This method is particularly useful for preparing aryl and vinyl lithium reagents.Catalyst in Asymmetric Synthesisn-BuLi is used as a catalyst in asymmetric synthesis and cross-coupling reactions, facilitating the formation of carbon-carbon bonds and other transformations essential for constructing complex molecules.Carbon-Carbon Bond Formationn-Butyllithium is employed in the addition to carbonyl compounds, aiding in the synthesis of aldehydes and ketones. It can also react with dialkyl amides to form new carbon-carbon bonds.High-Purity Reagent for Specialty PolymersHigh-purity n-BuLi solutions are used in the production of specialty polymers and in continuous flow chemistry systems, where rapid reaction kinetics are required.Hydrocarbonation Catalystn-Butyllithium acts as a catalyst in the synthesis of new chemicals used in rubber production, pharmaceuticals, flavor synthesis, and liquid crystal materials.Detailed Photos CertificationsPackaging & ShippingOur Advantages Company ProfileFAQQ1: Can I get some samples?
