Descripción general

Tetrahydropyran (THP) is a saturated cyclic ether. It is commonly used as a solvent in organic synthesis because of its strong hydrophobicity and low vaporization temperature, which enable easy recovery and reuse of the solvent. This makes the entire synthetic process more environmentally friendly.

Aplicación

Tetrahydropyran can be used as a solvent in various classical organic reactions such as radical reactions, palladium-catalyzed coupling, and Grignard reactions.
