Propyl isothiocyanate is widely used in the agricultural industry as a natural pesticide due to its ability to deter and control pests. It is effective against a variety of insects and nematodes, making it a valuable component in organic farming practices. Additionally, it is utilized in the food industry as a flavoring agent, imparting a pungent, mustard-like taste to certain products. In research, it serves as a biochemical tool to study the effects of isothiocyanates on cellular processes, particularly in cancer research, where its potential anti-carcinogenic properties are explored. Its strong antimicrobial properties also make it useful in preserving food and preventing spoilage.
