Acetylpropionyl, also known as acetyl propionyl or 2,3-pentanedione, [1] is an organic compound, specifically a diketone. [2] Uses for acetylpropionyl include as a: Solvent for cellulose acetate, paints, inks, and lacquers; Starting material for dyes, pesticides, and drugs
The (E) isomer is classically obtained from the 3-chloropentanone by dehydrohalogenation. [6]It can also be obtained by dehydration of 4-hydroxy-pentan-2-one using oxalic acid as a catalyst.
1,2-Cyclopentanedione is the organic compound with the formula (CH 2) 3 (CO) 2.It is one of two isomeric cyclopentanediones, the other being 1,3-cyclopentanedione.It was first prepared by base-induced condensation of di ethylglutarate with diethyloxalate, followed by hydrolysis of the resulting diketodiester followed by decarboxylation.

Fragrance bottles. An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor.For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose.
Pentenoic acid is any of five mono-carboxylic acids whose molecule has an unbranched chain of five carbons connected by three single bonds and one double bond.That is, any compound with one of the formulas HO(O=)C−CH=CH−CH 2 −CH 3 (2-pentenoic), HO(O=)C−CH 2 −CH=CH−CH 3 (3-pentenoic), or HO(O=)C−CH 2 −CH 2 −CH=CH 2 (4-pentenoic).
It is one of many products from the pyrolysis of lignocellulose. [4]It is used in flavors and perfumery for its maple- or caramel-like odor. [5] It contributes to the flavor or odor of many foods including wines, coffee, paprika, and salmon.
Methylene-interrupted polyenes are 1,4-pentadiene groups found in polyunsaturated fatty acids linoleic acid, α-linolenic acid, and arachidonic acid.These pentadiene derivatives are susceptible to lipid peroxidation, far moreso than monounsaturated or saturated fatty acids.
