What is Benzyl Isothiocyanate?

Benzyl isothiocyanate (BITC) is a naturally occurring organic compound with the molecular formula C8H7NS and molecular weight of 149.21 g/mol. Its CAS number is 622-78-6. This compound is classified as an isothiocyanate—a family of sulfur-containing compounds known for their distinctive pungent taste and numerous biological activities.

BITC is found naturally in cruciferous vegetables and is particularly abundant in plants of the Brassicaceae family, including mustard, radish, and wasabi. It is responsible for the characteristic pungent flavor of these plants and is released when plant cells are damaged through cutting or chewing, due to the action of the enzyme myrosinase on glucosinolate precursors.
