Dichloroacetic acid (DCA) is a colorless, odorless liquid that is a derivative of acetic acid. It contains two chlorine atoms attached to the carbon chain, which gives it unique chemical properties. DCA is primarily used in industrial applications, such as in the production of herbicides and as a solvent. In addition to its industrial uses, dichloroacetic acid has been studied for its potential therapeutic effects, particularly in cancer treatment. Research suggests that it may help inhibit tumor growth by affecting cellular metabolism. However, its use in medicine is still under investigation, and safety concerns remain.
