2-Butynoic acid is used as an intermediate in organic synthesis and pharmaceuticals. It is used as a synthon in various reactions, which includes cylcoalkylation of phenols to flavones and chromones. It is involved in the cyclization of gamma-butyrolactones. It is also used in the synthesis of Z-trisubstituted olefins through μ-alkylation. It plays an important role in the preparation of chirally pure 1,2,3,4-tetrahydroisoquinoline analogs, which finds application as anti-cancer agents.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
