Methacrolein, or methacrylaldehyde, is an unsaturated aldehyde. It is a clear, colorless, flammable liquid.Methacrolein is one of two major products resulting from the reaction of isoprene with OH in the atmosphere, the other product being Methyl vinyl ketone (MVK, also known as butenone). These compounds are important components of the atmospheric oxidation chemistry of biogenic chemicals, which can result in the formation of ozone and/or particulates.

It is present in cigarette smoke.Industrially, the primary use of methacrolein is in the manufacture of polymers and synthetic resins.Exposure to methacrolein is highly irritating to the eyes, nose, throat and lungs.The essential oil of the plant Big Sagebrush (Artemisia tridentata) contains 5% methacrolein.

An unsaturated aldehyde used in the manufacture of polymers and synthetic resin. Cancer studies revealed consumption and release of this volatile organic compound in human small cell lung cancer line, a potential cancer biomarker. Methacrolein was used to study the effect of parts per billion levels of limonene oxidation products and the terpene oxidation product, methacrolein on human eye blink frequency. It was also used in determination of rate constants and the products of the reactions between atomic chlorine and acrolein, methacrolein and methyl vinyl ketone.
