CAS NO: 59-92-7

L-DOPA (L-3,4-dihydroxyphenylalanine) is a naturally occurring amino acid and a precursor to several important neurotransmitters, including dopamine, norepinephrine, and epinephrine. Its chemical formula is C9H11NO4, and its CAS number is 59-92-7. L-DOPA is commonly used in the treatment of Parkinson's disease, as it can cross the blood-brain barrier and be converted into dopamine, which is a neurotransmitter that is depleted in individuals with Parkinson's disease. It is also used in the production of certain types of pigments and dyes, and as a research tool for studying the role of dopamine in the brain and nervous system. L-DOPA is usually administered orally as a medication or supplement and can cause side effects such as nausea, vomiting, and low blood pressure.
