(R)-4-Propyldihydrofuran-2(3H)-one
1. Basic Information
Name: (R)-4-Propyldihydrofuran-2(3H)-one
CAS No.: 63095-51-2
Molecular Formula: C7H12O2
Molecular Weight: 128.17
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless transparent oily liquid
- Odor: Mild creamy, coconut and lactone fragrance
- Solubility: Soluble in CH3OH, C2H5OH, acetone, edible oils; slightly soluble in hot H2O; insoluble in aliphatic alkanes
- Boiling Point: 210–215 °C
- Hygroscopicity: Non-hygroscopic under normal humidity
- Aqueous Characteristic: Neutral chiral lactone, weak ester aroma in aqueous dilution
Chemical Properties
- Molecular Structure: Chiral five-membered γ-lactone ring with n-propyl substituent at the 4-position, R configuration chiral carbon
- Lactone Hydrolysis: Stable under neutral and weak acidic conditions; hydrolyzes into corresponding hydroxycarboxylic acid under strong alkaline heating
- Oxidation Stability: Slightly yellowed after long-term exposure to air and ultraviolet light
- Thermal Stability: Stable within conventional flavor processing temperature range below 150 °C
- Photostability: Moderately sensitive to UV light; prolonged illumination generates trace oxidation impurities
- Compatibility: Good miscibility with most edible flavors, solvents and cosmetic oil phases; incompatible with concentrated strong alkali and strong oxidants
3. Main Application Fields

Safety Warning
Mild irritant lactone liquid. Vapor irritates eyes and respiratory tract; prolonged skin contact may cause slight redness. Wear chemical-resistant gloves and protective goggles with sufficient ventilation during operation. Store separately from fire and static electricity sources. Waste liquid belongs to flammable organic hazardous waste and needs centralized solvent recovery disposal.
