Description

Dl-Dopa CAS NO 63-84-3 is a synthetic racemic mixture of the amino acid derivative DOPA (3,4-dihydroxyphenylalanine). This compound serves as a critical chiral intermediate and biochemical precursor in advanced pharmaceutical synthesis and research. It is essential for manufacturers and R&D facilities in the pharmaceutical, biotechnology, and fine chemical sectors requiring a high-purity building block for neurological and metabolic agents.

Application

• Pharmaceutical Intermediate: Key starting material or chiral precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting neurological pathways.
• Biochemical Research: Used as a standard or reagent in enzymatic studies, neurotransmitter research, and metabolic pathway analysis.
• Reference Standard: Serves as a certified reference material (CRM) for quality control and analytical method development in pharmaceutical laboratories.
• Asymmetric Synthesis: Employed in the development and scale-up of stereoselective synthesis processes for producing enantiomerically pure compounds.
• Nutritional Supplement Research: Investigated as a component in studies related to amino acid metabolism and supplementation.
