Appearance: Cyclopentanone is a colourless to light yellow transparent liquid with a pleasant minty odour.
Melting point: The melting point of cyclopentanone is about -51ºC, the specific value may vary slightly due to different literature or experimental conditions.
Boiling point: The boiling point of cyclopentanone is 130~131ºC, again may vary according to different experimental conditions.
Density: The density of cyclopentanone is about 0.951g/cm³ (25°C) and the relative density (water=1) is 0.95.
Refractive index: The refractive index of cyclopentanone is 1.437 (20°C).
Solubility: Cyclopentanone is insoluble in water, but soluble in most organic solvents such as ethanol, ether and acetone. Its solubility in water is low, slightly soluble in water.
Flash point: The flash point of cyclopentanone is about 30.5°C, which means that enough vapour can be produced at a lower temperature to mix with air to form a flammable mixture.
