Description

L-Tyrosine Hydrochloride is the hydrochloride salt form of the essential amino acid L-Tyrosine, a critical building block for proteins and neurotransmitters. This high-purity compound is valued for its enhanced stability and solubility compared to the free amino acid, making it a preferred ingredient in demanding formulations. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and food and beverage industries for its role in supporting cognitive function, mood regulation, and as a biochemical precursor.

Application

• Pharmaceutical Intermediates: Used as a key chiral starting material or intermediate in the synthesis of active pharmaceutical ingredients (APIs), including L-DOPA and thyroid hormones.
• Dietary Supplements & Nutraceuticals: Incorporated into capsules, tablets, and powders aimed at supporting cognitive health, stress relief, and mood enhancement.
• Clinical Nutrition & Parenteral Solutions: An essential component in amino acid infusion solutions and specialized medical nutrition products for patients with specific dietary needs.
• Food & Beverage Fortification: Used to fortify foods and beverages, contributing to protein quality and serving as a nutritional additive.
• Biochemical Research & Cell Culture: Serves as a defined nutrient in cell culture media and as a standard/reagent in various biochemical and microbiological research applications.
• Cosmetic & Personal Care: Found in certain skincare formulations for its potential role as an antioxidant and in supporting skin protein synthesis.

Quality Control

Our L-Tyrosine Hydrochloride is manufactured under strict quality management systems. It is typically produced to meet or exceed standards such as USP, EP, and FCC for relevant grades, ensuring suitability for pharmaceutical, food, and supplement applications. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your regulatory and quality assurance needs.

Storage

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