Diallyl disulfide (DADS), identified by CAS number 2179-57-9, is an organosulfur compound that holds significant importance across various industrial sectors, particularly in pharmaceuticals and flavors. Its chemical and physical characteristics are key to its diverse applications. This article delves into the essential properties of DADS and provides insights into its sourcing and manufacturing, highlighting the role of NINGBO INNO PHARMCHEM CO.,LTD. as a reliable diallyl disulfide manufacturer in China.

Chemically, DADS, also known as 2-propenyl disulfide, has the formula C6H10S2 and a molecular weight of 146.27. It presents as a pale yellow liquid with a strong, characteristic garlic-like odor. Its flash point is around 42.4±25.8 °C, indicating it is a combustible liquid requiring careful handling. A crucial characteristic is its insolubility in water, stemming from its non-polar nature, which makes it soluble in organic solvents like hexane and toluene. This property is particularly beneficial for its use in oil-based formulations and as a pharmaceutical intermediate where solubility in organic media is often required. Understanding these chemical properties is fundamental for its effective use in synthesis and formulation.

The production of diallyl disulfide can be achieved through various methods, often starting from natural sources like garlic or through synthetic pathways involving compounds like sodium disulfide and allyl halides. Industrial synthesis typically involves controlled temperature conditions, often under an inert atmosphere, to maximize yield and purity. However, achieving exceptionally high purity and separating DADS from closely related compounds can be a manufacturing challenge. For instance, steam distillation of garlic bulbs yields concentrated oils rich in DADS, but commercial products often have a purity around 80-99%. As a diallyl disulfide supplier, NINGBO INNO PHARMCHEM CO.,LTD. places a strong emphasis on quality control throughout the manufacturing process to achieve the high assays (≥99.0%) required by our clients in pharmaceutical and research applications.

The applications of DADS are broad, ranging from its role as a pharmaceutical intermediate in the synthesis of active pharmaceutical ingredients (APIs) to its use as a food additive and flavor enhancer. Its potent biological activities, including anticancer and antioxidant effects, also drive its use in various research settings. The sourcing and availability of DADS are critical for industries relying on its unique properties. China has emerged as a significant hub for the production of fine chemicals, including DADS, leveraging both its natural resources and advanced chemical engineering capabilities.

In conclusion, diallyl disulfide is a compound with a distinct chemical profile and valuable industrial applications. Its properties make it a sought-after ingredient for flavors, fragrances, and critically, as a pharmaceutical intermediate.
