Description

Widely used hydroxyl-protecting reagent3,4-Dihydro-2H-pyran is used as a hydroxyl-protecting reagent in organic synthesis. It acts as an intermediate in synthetic chemistry. It is used to protect various reactive functional groups. It is involved in the polymerization reaction either alone or with unsaturated compound and finds application in polymer industries. Further, it is employed in the preparation of bicyclic compounds of epoxide-fused, halo compounds and allenic alcohols.

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.
