Crotonic acid is an unsaturated carboxylic acid and an organic compound with a double bond in its structure, giving it distinctive chemical reactivity. It is typically manufactured by the oxidation of crotonaldehyde or via catalytic processes involving butadiene. Crotonic acid’s trans isomer (the most stable form) is used as a precursor in polymer production, especially in specialty plastics and resins.
