A dihydroxyphenyl compound is a type of organic molecule that contains a phenyl ring, which is a six-carbon aromatic structure, along with two hydroxyl groups (-OH) attached to it. These compounds are important in various chemical reactions and can be found in many natural and synthetic substances, including some dyes and pharmaceuticals. One well-known example of a dihydroxyphenyl compound is dihydroxyphenylalanine (often abbreviated as DOPA), which is an amino acid precursor to the neurotransmitter dopamine. Dihydroxyphenyl compounds play significant roles in biological processes and are studied for their potential therapeutic applications.
