3,4-Dihydro-2H-pyran

Description:

3,4-Dihydro-2H-pyran is a cyclic ether with the molecular formula C5H8O. It features a six-membered ring structure that includes one oxygen atom and five carbon atoms, with two of the carbon atoms being sp3 hybridized, contributing to its saturated nature. This compound is characterized by its colorless to pale yellow liquid form and has a mild, pleasant odor. It is known for its reactivity, particularly in organic synthesis, where it can serve as a building block for various chemical transformations, including the formation of more complex molecules. 3,4-Dihydro-2H-pyran is soluble in organic solvents such as ethanol and ether, but it has limited solubility in water due to its hydrophobic characteristics. The compound is also notable for its potential applications in the synthesis of pharmaceuticals and agrochemicals. Safety considerations include handling it in well-ventilated areas and using appropriate personal protective equipment, as it may pose health risks upon exposure.
