1-(tetrahydro-2H-pyran-4-yl)ethanol; CAS No.: 66956-74-9; 1-(tetrahydro-2H-pyran-4-yl)ethanol. PROPERTIES: This tetrahydropyran-substituted ethanol has molecular formula C7H12O2. It appears as a colorless liquid. The 1-(tetrahydro-2H-pyran-4-yl)ethanol demonstrates moderate solubility in water and good solubility in common organic solvents like ether and acetone. Its boiling point ranges between 160-165 C, and it has a molecular weight of approximately 128.17 g/mol. When handling, care should be taken to avoid skin contact and use of proper respiratory protection. Storage should be in a tightly sealed container at room temperature, protected from light and moisture. The compound is sensitive to strong oxidizing agents and may form peroxides upon prolonged storage. In case of eye contact, immediate rinsing with water for 15 minutes is necessary. APPLICATIONS: The 1-(tetrahydro-2H-pyran-4-yl)ethanol serves as a valuable intermediate in the synthesis of flavor and fragrance compounds where the tetrahydropyran framework provides essential olfactory properties (as reported in flavor chemistry literature). Additionally, the compound functions as a building block in the preparation of specialty chemicals for polymer modifiers, enhancing thermal stability of polymers as described in materials science journals. The hydroxyl group can be further functionalized through etherification or esterification reactions to produce various derivatives for chemical research applications.
