Appearance:3,4-dihydrocoumarin is a white to pale yellow clear oily liquid with a sweet odor. Solidifies around room temperature. (NTP, 1992)
Density:1.169 g/cm3 @ Temp: 18 °C
Melting Point:25 °C
Boiling Point:272 °C
Flash Point:>230 °F
Refractive Index:1.562
Water Solubility:H2O: insoluble
Storage Conditions:Store below +30°C.
Vapor Pressure:13.4 mm Hg at 77° F ; 19.5 mm Hg at 108° F; 27.4 mm Hg at 145° F (NTP, 1992)
Odor:Herbal
Taste:Sweet then bitter
Experimental Properties:Congealing point: 23 °C
Air and Water Reactions:Solutions of the chemical in water are stable for less than two hours. Insoluble in water.
Reactive Group:Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Reactivity Profile:3,4-DIHYDROCOUMARIN is a lactone (behaves as an ester). Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This chemical may hydrolyze under alkaline or acidic conditions. (NTP, 1992)
