Pentan-2-one or 2-pentanone or methyl propyl ketone is a achromatic aqueous ketone with an odor akin that of acetone. Its blueprint is C5H10O. It is sometimes acclimated in actual baby amounts as a accretion aliment additive. Two added ketones, 3-pentanone and methyl isopropyl ketone are isomers of 2-pentanone.
Chemical Properties
colourless liquid
General Description
A bright achromatic aqueous with the odor of barb polish. Flash point 45°F. Less close than baptize and acrid in water. Hence floats on water. Density 0.809 g / cm3. Vapors added than air.
Air & Baptize Reactions
Highly flammable. Acrid in water.
2-Pentanone is adverse with acerbic agents, able bases and abbreviation agents. Reacts berserk with bromine trifluoride.
2-Pentanone inhibited both prostaglandin assembly and COX-2 protein announcement in animal colon blight cells. A absorption of 400 mumol/l 2-pentanone inhibited the prostaglandin assembly by 56.9+/-12.9% which is in the aforementioned ambit as the advertence admixture NS398 (59.8+/-7.6%). The two accomplished concentrations of 2-pentanone were added analyzed by Western blot, and 400 micromol/l and 200 micromol/l 2-pentanone resulted in a 53.3+/-9.6% and +/-27.1% abridgement of the COX-2 protein levels respectively. Added studies on flavouring compounds, for archetype 2-pentanone, as colon blight chemopreventives would be actual valuable, and such after-effects may accord to approaching comestible recommendations.
