Lindlar catalyst is widely used in organic synthesis for the selective hydrogenation of alkynes to cis-alkenes. This partial hydrogenation is crucial in the production of fine chemicals and pharmaceuticals, where specific stereochemistry is required. It is particularly valuable in synthesizing complex molecules, such as natural products and bioactive compounds, where maintaining the cis-configuration is essential. Additionally, it finds applications in the preparation of intermediates for polymers, agrochemicals, and specialty chemicals. Its selectivity and efficiency make it a preferred choice in controlled hydrogenation reactions.
