Tetrahydrothiopyran-4-One
Tetrahydrothiopyran-4-One (CAS: 1072-72-6) is a colourless to pale yellow sulfur-containing cyclic ketone that serves as a versatile synthetic building block. The ketone reacts with amines, hydrazines and organometallics in the usual way, while the ring sulfur can be oxidised to sulfoxide or sulfone and can coordinate to metals, so a single starting material gives access to a wide range of products. It is used to prepare pharmaceuticals, agrochemicals, flavour-active thiacyclic compounds and specialty ligands, and it is also a useful intermediate for spiro and bridged sulfur heterocycles. The liquid is supplied at 98% purity.
• Pharmaceutical synthesis: a building block for sulfur-containing drug intermediates and bioactive heterocycles.
• Agrochemical intermediates: used in the preparation of crop-protection actives containing thiacyclic rings.
• Flavour and fragrance chemistry: applied in the synthesis of sulfur-containing aroma compounds.
• Specialty chemicals and ligands: a precursor for sulfoxide, sulfone and metal-coordinating thiacyclic derivatives.
