Crotonic

Cro`ton´ic


a.1.Of or pertaining to, or derived from, a plant of the genus Croton, or from croton oil.
Crotonic acid
(Chem.) a white crystalline organic acid, C3H5.CO2H, of the ethylene, or acrylic acid series. It was so named because formerly supposed to exist in croton oil. Also, any acid metameric with crotonic acid proper.
