Description

L-Tyrosine is a non-essential, proteinogenic amino acid that serves as a crucial metabolic precursor for the synthesis of key neurotransmitters and hormones. Its significance lies in its role in supporting cognitive function, mood regulation, and the production of melanin and thyroid hormones. This high-purity compound is essential for manufacturers in the pharmaceutical, nutraceutical, food & beverage, and cosmetic industries, where it is used in dietary supplements, infusion solutions, and as a biochemical intermediate.

Application

• Pharmaceutical Intermediates: As a key raw material for the synthesis of L-DOPA (Levodopa), a primary treatment for Parkinson's disease.
• Dietary Supplements & Nutraceuticals: Incorporated into formulations aimed at supporting cognitive health, stress relief, and mood enhancement.
• Infusion Solutions & Parenteral Nutrition: Used as a component in amino acid solutions for clinical nutrition and critical care.
• Food & Beverage Fortification: Added to health foods, sports nutrition products, and functional beverages as a nutritional supplement.
• Biochemical Research & Cell Culture: Serves as a defined component in microbial culture media and as a reagent in life science research.
• Cosmetic Ingredients: Utilized in skincare formulations for its role as a precursor in melanin synthesis.

Quality Control

Our L-Tyrosine is manufactured under strict quality management systems. It can be produced to meet various pharmacopoeial standards, including USP, EP, and JP, as well as food-grade specifications like FCC. Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing all relevant specifications and test results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture.
