Description

Tyrosine CAS NO 55520-40-6 is a vital aromatic amino acid that serves as a fundamental building block for proteins and neurotransmitters. Its significance lies in its role as a biochemical precursor for critical compounds like dopamine, epinephrine, and thyroid hormones, making it essential for metabolic and neurological functions. This high-purity ingredient is primarily needed by manufacturers in the pharmaceutical, nutraceutical, and research sectors for applications ranging from dietary supplements to advanced biochemical synthesis.

Application

• Pharmaceutical Intermediates: Key raw material in the synthesis of L-DOPA (Levodopa) for Parkinson's disease treatment and other active pharmaceutical ingredients (APIs).
• Dietary Supplements & Nutraceuticals: Used in formulations aimed at supporting cognitive function, mood regulation, and stress response due to its role in neurotransmitter production.
• Biochemical Research & Cell Culture: Essential component in media formulations for mammalian cell culture and as a substrate in various enzymatic and metabolic studies.
• Precursor for Fine Chemicals: Serves as a starting material for the production of melanin, alkaloids, and other specialty organic compounds.
• Food & Beverage Fortification: Incorporated into nutritional products and medical foods designed for specific dietary management and amino acid supplementation.
