Description Research Excerpts Clinical Trials Roles Classes Pathways Study Profile Bioassays Related Drugs Related Conditions Protein Interactions Research Growth Market Indicators

Isothiocyanic acid, also known as thiocyanic acid, is a colorless liquid with a pungent odor. It is a strong acid and a highly reactive compound. It is not found in its pure form in nature but is often produced as a derivative of other compounds. Isothiocyanic acid is produced commercially by the reaction of carbon disulfide with ammonia. It is used in the production of various chemicals, including pesticides, herbicides, and pharmaceuticals. Isothiocyanates, derivatives of isothiocyanic acid, are found in a variety of plants, particularly in cruciferous vegetables like broccoli, cabbage, and cauliflower. These compounds have been shown to have a variety of biological activities, including anticancer, antimicrobial, and antioxidant properties. Isothiocyanates are studied for their potential health benefits and their role in preventing chronic diseases. They have been shown to inhibit the growth of cancer cells and protect against heart disease and stroke. The research into isothiocyanates is ongoing, with scientists investigating their mechanisms of action and their potential as therapeutic agents. '
