Methyl glyoxal hydrocarbon

Dialdehydes are important, photochemically reactive intermediates, formed from a wide range of precursors, most importantly isoprene and aromatic hydrocarbons. Glyoxal is formed following reaction of OH with hydroxyacetaldehyde, an intermediate in isoprene oxidation, as discussed previously. Methylglyoxal is formed following reaction of O3 with both methyl vinyl ketone and methacrolein, major intermediates in isoprene oxidation, and following reaction of methacrolein with OH.
