Used as an organic solvent and as an intermediate in pharmaceutical and specialty chemical synthesis. It is also used to prepare tetrahydropyranyl (THP) protecting groups for alcohols and other functional groups.

Primarily used as a solvent and as a building blockprotecting-group precursor in organic synthesis helping protect sensitive functional groups during multi-step reactions.

Tetrahydropyran is a six-membered cyclic ether with one oxygen atom in the ring. It is a colorless flammable liquid with an ether-like odor and is soluble in many organic solvents.
