CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID
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 .
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.

Colorless to light yellow liquid. Floats on water. Freezing point is 21°F.
Ketones, such as 5-Nonanone, 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].
Inhalation causes irritation of nose and throat. Ingestion causes irritation of mouth and stomach. Contact with eyes or skin causes irritation.
Reactivity with Water No reaction; Reactivity with Common Materials: May attack some forms of plastics; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
