It is a clear, yellowish liquid which boils at 138–139 °C (for the typical 80% purity) and has its flash point at 50 °C, a density of about 1.0 g/mL and a vapor pressure of 1 mmHg at 20 °C. It is non-polar; therefore, diallyl disulfide is insoluble in water and is soluble in fats, oils, lipids, and non-polar solvents such as hexane or toluene. Diallyl disulfide can be readily oxidized to allicin with hydrogen peroxide or peracetic acid. Allicin in t…
