Pharmaceutical Chemistry
L-Leucine
Formula:
C₆H₁₃NO₂
GOST/CAS:
CAS: 61-90-5
L-Leucine (a highly purified, branched-chain essential amino acid, BCAA) is a key component acting as the primary agent for stimulating protein synthesis, repairing muscle tissue, and regulating metabolic processes. The product is a homogenous white crystalline powder, sparingly soluble in water. Due to its supreme purity and strict compliance with international pharmacopoeia standards, L-Leucine is indispensable in the manufacture of pharmaceuticals, infusion solutions, specialized sports nutrition, and dietary supplements.
Applications
Pharmaceutical Manufacturing: Used as an Active Pharmaceutical Ingredient (API) in the production of complex amino acid formulations, oral dosage forms, and infusion solutions for parenteral nutrition.
Dietary Supplements & Sports Nutrition: Acts as the core element in BCAA amino acid complexes designed to accelerate muscle fiber regeneration, prevent catabolism, and support anabolic processes.
Food Industry: Utilized as a functional and nutritional additive to fortify dietary and specialized food products with an enhanced amino acid profile.
Biotechnology & Cosmeceuticals: Included in cell culture media formulations, as well as premium cosmetic products to stimulate skin regeneration and collagen synthesis.
Key Advantages
Pharma Purity (USP/EP Standards): The product undergoes a multi-stage purification process, ensuring strict limits on impurities and heavy metals, and complete absence of endotoxins.
High Bioavailability: Readily absorbed by the body, rapidly entering the metabolic cycle and acting as the main trigger of the mTOR signaling pathway for protein synthesis.
Formulation Stability: Excellent retention of physical and chemical properties within dry blenders, capsules, and tablet forms; demonstrates outstanding compatibility with other amino acids and vitamins.
Eco-Friendly & Safe: Produced via microbiological synthesis (fermentation) from natural plant-based raw materials, contains no toxic chemical residues, and is entirely safe for human consumption.
Storage & Transportation
- Store in dry, clean, and well-ventilated warehouses in the manufacturer's tightly sealed original packaging, away from heat sources and foreign odors.
- Recommended storage temperature: +5°C to +25°C. Avoid sudden temperature fluctuations to prevent condensation.
- Protect from direct sunlight and moisture exposure, as the finely milled amino acid powder is highly sensitive to humidity.
- Transportation is permitted by all types of covered transport vehicles, strictly adhering to sanitary and hygienic regulations for pharmaceutical and food raw materials. Shelf life: 3 years from the date of manufacture.
