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.]
