3-Methyl-2-pentanone (methyl sec-butyl ketone) is an aliphatic ketone and isomer of 2-hexanone. [2] References This page was last edited on 17 November 2024, at 23: ...
3-Methyl-3-penten-2-one is an unsaturated aliphatic ketone. It is an isomer of mesityl oxide and isomesityl oxide. It is a precursor of 3-methyl-2-pentanone (methyl sec-butyl ketone) and is obtained by acid-catalyzed dehydration of 4-hydroxy-3-methyl-2-pentanone. It is used as an intermediate in organic chemistry syntheses. [1]
3-Pentanone (also known as diethyl ketone) is a simple, symmetrical dialkyl ketone. It is a colorless liquid ketone with an odor like that of acetone . It is soluble in about 25 parts water, but miscible with organic solvents.
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 ...
Pentanone may refer to the following ketones containing five carbon atoms: 2-Pentanone (Methyl propyl ketone, MPK) 3-Methyl-2-butanone (Methyl isopropyl ketone, MIPK)
The McLafferty rearrangement is a reaction observed in mass spectrometry during the fragmentation or dissociation of organic molecules. It is sometimes found that a molecule containing a keto-group undergoes β-cleavage, with the gain of the γ-hydrogen atom, as first reported by Anthony Nicholson working in the Division of Chemical Physics at the CSIRO in Australia.

3-Penten-2-one occurs naturally in the berries of two species of Aronia melanocarpa. [7] It has also been found in other plants and foods such as tomatoes, cocoa, tea, and potato chips. [5] 3-Penten-2-one can be used for the synthesis of other compounds such as the alkaloids senepodine G and cermizine C, for example. [7]
2-Pentanone or methyl propyl ketone (MPK) is a ketone and solvent of minor importance. It is comparable to methyl ethyl ketone , but has a lower solvency and is more expensive. [ 5 ] It occurs naturally in Nicotiana tabacum (Tobacco) [ 6 ] and blue cheese as a metabolic product of Penicillium mold growth.
