Butanone, also known as methyl ethyl ketone (MEK) or ethyl methyl ketone, [a] is an organic compound with the formula CH 3 C(O)CH 2 CH 3. This colorless liquid ketone has a sharp, sweet odor reminiscent of acetone .
Methyl vinyl ketone (MVK, IUPAC name: butenone) is the organic compound with the formula CH 3 C(O)CH=CH 2. It is a reactive compound classified as an enone , in fact the simplest example thereof. It is a colorless, flammable, highly toxic liquid with a pungent odor.
Raspberry ketone occurs in a variety of fruits, including raspberries, cranberries, and blackberries. [3] It is detected and released by orchid flowers, e.g. Dendrobium superbum (syn D. anosmum), [4] and several Bulbophyllum species [5] [6] [7] to attract raspberry ketone-responsive male Dacini fruit flies.

Like other butanols, butan-2-ol has low acute toxicity. The LD 50 is 4400 mg/kg (rat, oral). [6]Several explosions have been reported [7] [8] [9] during the conventional distillation of 2-butanol, apparently due to the buildup of peroxides with the boiling point higher than that of pure alcohol (and therefore concentrating in the still pot during distillation).
3-Methyl-2-butanone (methyl isopropyl ketone, MIPK) is a ketone and solvent of minor importance. It is comparable to MEK ( Methyl ethyl ketone ), but has a lower solvency and is more expensive. [ 2 ]
3,4-Methylenedioxyphenylpropan-2-one [1] or piperonyl methyl ketone (MDP2P or PMK) is a chemical compound consisting of a phenylacetone moiety substituted with a methylenedioxy functional group. It is commonly synthesized from either safrole (which, for comparison, is 3-[3,4-(methylenedioxy)phenyl]-2-propene) or its isomer isosafrole via ...
tert-Amyl alcohol (TAA) or 2-methylbutan-2-ol (2M2B), is a branched pentanol. Historically, TAA has been used as an anesthetic [ 3 ] and more recently as a recreational drug . [ 4 ] TAA is mostly a positive allosteric modulator for GABA A receptors in the same way as ethanol . [ 5 ]
