Widely used as a strong base and nucleophile in organic synthesis, particularly in the formation of carbon-carbon bonds. It is essential in the polymerization of dienes for producing synthetic rubbers and plastics. Commonly employed in the preparation of organolithium reagents, which are intermediates in various chemical reactions. Utilized in the pharmaceutical industry for the synthesis of complex molecules and active pharmaceutical ingredients. Also applied in the production of fine chemicals and specialty materials. Handled with extreme care due to its high reactivity and pyrophoric nature.
