[General Description]

Colorless to light yellow liquid. Floats on water. Freezing point is 21°F.
[Reactivity Profile]

Ketones, such as DI-N-BUTYL KETONE(502-56-7), are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. May attack some forms of plastics [USCG, 1999].
[Air & Water Reactions]

Highly flammable.
[Health Hazard]

Inhalation causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes or skin causes irritation.
[Chemical Properties]

5-Nonanone is a stable and colorless-to-light yellow liquid.
No human odor threshold was identified for 5-nonanone. However, Laska et al. demonstrated using a conditioning paradigm that the olfactory threshold of squirrel monkeys and pigtail caques for 5-nonanone is below 1 ppb .
[Chemical Properties]

CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID
[Uses]

5-Nonanone is used in preparation of 6-(1,2,4-oxadiazol-5-yl)chroman-4-one derivatives as S1P1 receptor modulators and methods for preparing them.
