Pharmaceutical Chemistry
L-Phenylalanine
Formula:
C₉H₁₁NO₂
GOST/CAS:
CAS 63-91-2
L-Phenylalanine (a high-purity essential amino acid) is a vital biological component acting as a key building block for the synthesis of proteins, neurotransmitters, and regulatory peptides in the human body. The product is a white or almost white crystalline powder, highly soluble in water and featuring an exceptional level of chemical purity. Due to its biological role as a precursor to dopamine, norepinephrine, and tyrosine, L-phenylalanine is indispensable in the production of a wide range of pharmaceuticals, infusion solutions, specialized dietary nutrition, and biologically active supplements (DI / supplements).
Applications
Pharmaceutical Industry: Utilized as an Active Pharmaceutical Ingredient (API) in complex amino acid solutions for parenteral nutrition. It is widely used in the manufacturing of nootropics, antidepressants, and formulations aimed at regulating psycho-emotional states.
Dietary Supplements & Sports Nutrition: Included in the formulations of mono- and complex supplements to enhance cognitive functions, focus, and memory, as well as in products designed for appetite control and weight management.
Specialized & Clinical Nutrition: Applied in the development of therapeutic and dietary food products, as well as formulas for recovery after prolonged illness and intense physical exertion (excluding products intended for individuals with phenylketonuria).
Synthesis of Sweeteners: Serves as the primary raw material component in the chemical synthesis of aspartame, a widely used low-calorie sugar substitute.
Key Advantages
Pharmaceutical Purity (Ph. Eur. / USP): Fully complies with strict international quality standards. Minimizing impurities guarantees maximum safety for both injectable and oral dosage forms.
High Bioavailability: Readily absorbed by the body, rapidly integrating into metabolic pathways and the synthesis of vital neurotransmitters.
Stable Physicochemical Properties: The fine crystalline structure ensures excellent free-flowing properties, high processability during encapsulation or tableting, and precise dosing throughout production cycles.
Safety & Eco-Friendliness: Produced via microbiological synthesis or environmentally clean chemical pathways, ensuring it remains free of toxic residual solvents when processed under GMP regulations.
Storage & Transportation
- Store in dry, clean, cool, and well-ventilated warehouse facilities in tightly closed original packaging, away from heat sources and foreign odors.
- Avoid direct sunlight exposure and moisture, as the product is hygroscopic under high-humidity conditions.
- Recommended storage temperature range: +5°C to +25°C.
- Transport is permitted by all types of covered transport while maintaining the required temperature conditions. The material is not classified as a dangerous good. Shelf life is 3 years from the date of manufacture.
