| | Propyl disulfide Usage And Synthesis |
| Chemical Properties | CLEAR COLURLESS TO PALE YELLOW LIQUID | | Chemical Properties | Propyl disulfide has a pungent, sulfur-like odor, with penetrating qualities like the odor of onion and garlic. | | Occurrence | Reported found in cabbage, onion, garlic, shallot, roasted onion, raw leek, heated leek, chive, nobiru, caucas,
Welsh onion, scallion, grilled and roasted beef and roasted peanut. | | Uses | Dipropyl disulfide is a BP-induced cancer inhibitor. | | Definition | ChEBI: Dipropyl disulfide is an organic disulfide where the alkyl groups specified are propyl. It is a component of the essential oils obtained from Allium. It has a role as a plant metabolite. | | Preparation | By boiling propyl bromide and Na2S2 in propyl alcohol; from iodine and n-propyl mercaptan; from propyl iodide and
sodium thiosulfate by way of sodium propyl thiosulfate, followed by heating. | | Taste threshold values | Taste characteristics at 10 ppm: alliaceous, sulfurous, green, vegetative and asefetida nuances. | | General Description | Dipropyl disulfide (DPDS) was an efficient scavenger of reactive oxygen species (ROS) at a lower concentration in both HL-60 and HepG2 cells. It prevents the oxidative DNA damage caused by N-nitrosopiperidine (NPIP) and N-nitrosodibutylamine (NDBA). |
