Tulipalin A, also known as α-methylene-γ-butyrolactone,^[1] is a naturally occurring compound found in certain flowers such as tulips and alstroemerias.^[2] Tulipalin A has the molecular formula C₅H₆O₂ and the CAS registry number 547-65-9.^[1] It is an allergen and has been known to cause occupational contact dermatitis, i.e. 'tulip fingers,' in some who are commonly exposed to it such as florists.^[3] More recent experiments with this compound have uncovered potential applications for it in the field of polymerization.^[4]^[5]
