Diallyl sulfide is widely used in the food industry as a flavoring agent due to its characteristic garlic-like aroma. It also exhibits antimicrobial properties, acting as a natural preservative to extend shelf life and prevent spoilage in foods. It is utilized in the production of synthetic garlic oils and seasonings. In the field of agriculture, it serves as a natural pesticide, effectively repelling pests and protecting crops. Additionally, diallyl sulfide has been studied for its potential health benefits, particularly in cancer prevention (especially gastrointestinal cancers) and cardiovascular health, due to its antioxidant, anti-inflammatory, and cell growth-inhibiting properties. It is also employed in the synthesis of organic compounds and as an intermediate in chemical research.
