Products Description
Diallyldisulfide (CAS 2179-57-9) is a key allergen naturally found in garlic (Allium sativum) and onions. This association is well supported by clinical patch-test evidence: among patients who had previously shown a positive reaction to garlic, all 13 who were further tested with diallyldisulfide in petrolatum also tested positive.

Products Application
The applications of diallyldisulfide are primarily concentrated in the food, pharmaceutical, and scientific research sectors, and can be grouped into three main categories:
1.Food Sector: As a natural flavor compound, diallyldisulfide is a key contributor to the characteristic pungent aroma of garlic, onions, and other Allium species. It is widely used as a flavoring agent in food products to enhance and reproduce these distinctive notes.
2.Pharmaceutical & Health Research: Diallyldisulfide exhibits notable biological activity. Studies indicate it may possess potential antibacterial and lipid-regulating properties, making it one of the reference compounds in the development of related health products and pharmaceuticals.
3.Allergy Research: As a major low-molecular-weight allergen in garlic, diallyldisulfide is frequently employed in clinical allergy testing, such as patch testing, to help diagnose individuals with garlic sensitivity.
