Dichloroacetic acid is primarily used in medical and pharmaceutical applications. It is investigated for its potential to treat certain metabolic disorders, particularly those involving lactic acidosis, by inhibiting pyruvate dehydrogenase kinase. This action helps in normalizing abnormal metabolic processes. Additionally, it has been explored in cancer research for its ability to induce apoptosis in certain types of cancer cells, making it a subject of interest in developing anticancer therapies. In dermatology, it is sometimes used in chemical peels to treat skin conditions like warts and hyperkeratosis due to its keratolytic properties. Beyond medical uses, it serves as an intermediate in the synthesis of various organic compounds in industrial chemistry.
