Diallyldisulfide CAS#2179-57-9

Basic Information

Diallyldisulfide

Diallyl disulfide is a sulfur-containing compound identified as a major low-molecular-weight allergen in garlic and onions. Its defined reactivity in petrolatum preparations makes it suitable for controlled reference formulations. It is used in allergy patch-test materials and in research involving garlic-related allergen mixtures. The compound is also considered alongside allylpropyl disulfide and allicin in studies of garlic constituents.
