Description

L-Threonine is an essential amino acid crucial for protein synthesis and metabolic functions in humans and animals. Its high purity and consistent quality make it a vital component for ensuring nutritional balance and product efficacy in various formulations. This product is primarily required by manufacturers in the animal feed, pharmaceutical, and food & beverage industries for its role in fortification and as a biochemical building block.

Application

• Animal Feed & Nutrition: A critical additive in poultry, swine, and aquaculture feed to optimize growth performance, improve feed efficiency, and support immune function.
• Pharmaceutical Intermediates: Used as a key raw material in the synthesis of active pharmaceutical ingredients (APIs) and intravenous nutrient solutions (amino acid infusions).
• Food & Beverage Fortification: Incorporated into dietary supplements, infant formula, and functional foods to enhance nutritional profiles and meet specific amino acid requirements.
• Microbiological & Cell Culture Media: Serves as a defined nutrient component in fermentation processes and cell culture media for the production of biologics and other fine chemicals.
• Cosmetic & Personal Care: Utilized in skincare formulations for its moisturizing properties and role in maintaining skin barrier function.

Quality Control

Our L-Threonine 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 comprehensive analytical testing, including assay, optical rotation, and impurity profiling. Certificates of Analysis (COA) are provided to ensure full traceability and compliance with your specific requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking.
