Used as a selective hydrogenation catalyst in organic synthesis, particularly in the reduction of alkynes to alkenes without over-reduction to alkanes. It is effective in fine chemical and pharmaceutical manufacturing where precise control of hydrogenation is required. The support on strontium carbonate enhances catalyst activity and selectivity compared to other supports. Commonly applied in the synthesis of intermediates for vitamins, fragrances, and specialty polymers. Also utilized in deprotection reactions in peptide and nucleotide chemistry due to its mild operating conditions.
