Chemical Properties
clear colorless to light yellow liquid
Chemical Properties
3-Methyl-2-butenal has an almond odor
Uses
3-Methyl-2-butenal is used in small quantities as food flavor in alcoholic beverages, chewing gums, confection frosting, frozen dairy, fruit ice, gelatin pudding, hard and soft candy and jam jelly. Used in daily flavor, and cosmetic flavor in perfumes. A starting material for the synthesis of vitamin A.
Definition
ChEBI: An enal consisting of but-2-ene with a methyl substituent at position 3 and an oxo group at position 1.
Taste threshold values
Taste characteristics at 25 ppm: sweet, fruity and green with a nutty and cherry background.
General Description
3-Methylcrotonaldehyde is an α, β-unsaturated aldehyde. Electrochemical dimerization of 3-methylcrotonaldehyde was reported. The hydrogenation of 3-methylcrotonaldehyde over Ru, Pt and Rh was investigated.
Purification Methods
This flammable oil oxidises readily and should be fractionated under N2. It should be stored under N2 and/or vacuum. The UV has max at 235.5nm. The semicarbazone has m 221-222o (from MeOH) and the 2,4-dinitrophenylhydrazone has m 184-185o (from MeOH). [Forbes & Skilton J Org Chem 24 436 1959, Beilstein 1 III 2990, 1 IV 3464.]
