Crotonaldehyde is a reactive unsaturated aldehyde. Chemical companies use it as a building block for fine chemicals and for sorbic acid, and alcohol users rely on it as an ethanol denaturant.
What Is Crotonaldehyde?
Crotonaldehyde (also known as 2-butenal or crotonal) has the molecular formula C4H6O. It is a pale-yellow liquid with a pungent smell, moderately soluble in water and miscible with alcohol and most organic solvents. The trans isomer is listed under CAS No. 4170-30-3, and mixed-isomer material under CAS No. 123-73-9.
Because it contains both a double bond and an aldehyde group, it is a versatile intermediate in organic synthesis. It is flammable and toxic, so it should only be handled by trained staff following the MSDS, with proper ventilation, protective equipment and closed storage away from heat and ignition sources.
