Product Informations

Dihydropyran, also known as tetrahydropyrn, is an organic compound with the chemical formula C5H10O. It is soluble in various organic solvents but only slightly soluble in water.

Applications: Dihydropyran has several applications in organic synthesis:
Protecting Group: It can be used as a protecting group for alcohols and amines in organic synthesis. By temporarily converting these functional groups into dihydropyran ethers, they can be selectively protected during specific reactions and subsequently restored to their original form.

Building Block: Dihydropyran serves as a versatile building block in the synthesis of various organic compounds. It can undergo different chemical transformations, such as oxidation, reduction, and functional group modification, to yield more complex molecules.

Flavor and Fragrance: Dihydropyran and its derivatives are used in the flavor and fragrance industry to impart a caramel-like or fruity aroma to food products, beverages, and perfumes.

Safety Considerations: Dihydropyran is generally considered to be of low toxicity. However, as with any chemical compound, it is important to handle it with appropriate safety precautions. Direct contact with the skin or inhalation of vapors should be avoided, and proper ventilation and personal protective equipment should be used when working with this compound.
