Allyl isothiocyanate (AITC) is the
organosulfur compound with the formula CH
2CHCH
2NCS. This colorless oil is responsible for the pungent taste of
mustard,
radish,
horseradish, and
wasabi. This pungency and the
lachrymatory effect of AITC is mediated through the
TRPA1 and
TRPV1 ion channels. It is slightly soluble in water, but more soluble in most organic solvents.
