Basic Info
Propyl Disulfide CAS 629-19-6 Manufacturer Supplier. Available in stock, sufficient inventory, one-stop service. Dipropyl disulfide (chemical formula: C₆H₁₄S₂, CAS number: 629-19-6) is an organic disulfide composed of two propyl groups (—C₃H₇) connected by a disulfide bond (—S—S—). The compound is a colorless to pale yellow liquid at room temperature with a strong pungent odor (similar to onion or garlic), insoluble in water but easily soluble in organic solvents (such as ethanol, ether). The disulfide bonds in its molecules have high reactivity and can be broken under reducing conditions to form thiols (such as propanethiol), or further formed under oxidizing conditions. Higher-order sulfides.
Dipropyl disulfide naturally exists in the volatile components of plants such as onions, garlic, and leeks, and is one of their characteristic flavor substances. In industry, it can be synthesized by the oxidation reaction of thiols (such as propanethiol).

Product Packaging
1. Food industry
(1) Food spices and seasonings
Naturally present in plants such as onions, garlic, and leeks, it is one of their characteristic flavor components.
Industrially used to prepare onion and garlic flavors, widely used in seasonings, convenience foods, meat products and sauces, providing a strong spicy flavor.
The dosage must be strictly controlled (ppm level), excessive use will cause odor.
(2) Food preservatives
It has an inhibitory effect on some bacteria and fungi and can be combined with other preservatives to extend the shelf life of food.
2. Agricultural chemistry
(1) Pesticide intermediates
As a key raw material for the synthesis of sulfur-containing pesticides (such as insecticides and fungicides), for example:
Preparation of thiocarbamate insecticides through derivatization.
After modification, it is used to control soil nematodes or storage pests.
The decomposition products (such as propyl mercaptan) have a repellent effect on some pests.
(2) Plant growth regulator
Low concentrations can stimulate seed germination or root development, but high concentrations may have an inhibitory effect.
3. Chemical Engineering and Materials Science
(1) Rubber Industry
Vulcanization accelerator: In rubber processing, disulfide bonds can participate in cross-linking reactions to improve the elasticity and aging resistance of rubber.
Antioxidant: Delays the hardening or cracking of rubber due to oxidation.
(2) Lubricant additives
Extreme pressure anti-wear agent: Under high temperature and high pressure conditions, disulfide bonds decompose to form iron sulfide films, reducing the wear of metal friction pairs (applicable to gear oils, cutting fluids, etc.).
(3) Organic synthetic building blocks
Used to prepare thiols, sulfonic acid compounds or other sulfur-containing functional molecules (such as pharmaceutical intermediates).
4. Medicine and biotechnology
(1) Antibacterial research
It has inhibitory activity against some Gram-positive bacteria and fungi and may be used in the development of local antibacterial preparations.
It is necessary to pay attention to its cytotoxicity and structural modification is required to reduce side effects.
(2) Drug synthesis
As a reagent for introducing sulfur-containing groups, it is used to synthesize anti-tumor or anti-inflammatory drugs (such as thiol prodrugs).
