Pharmaceutical Chemistry
L-Serine
Formula:
C3H7NO3
GOST/CAS:
CAS 56-45-1
L-Serine (pharmaceutical grade) is a highly purified non-essential amino acid that plays a critical role in the biosynthesis of proteins, purines, pyrimidines, and other key elements of cellular metabolism. The product is a white crystalline powder that is highly soluble in water. Due to its exceptional purity and strict compliance with international pharmacopoeia standards, L-Serine is an indispensable component in the production of parenteral nutrition solutions, as an active pharmaceutical ingredient (API) for neurological medications, and as a vital nutrient in biotechnological processes and cell culture media preparation.
Applications
Parenteral and Enteral Nutrition: Used as an essential component in complex amino acid solutions for intravenous administration, providing the body with plastic material required for tissue repair.
Pharmaceutical Manufacturing (API): Applied in the synthesis of drugs designed to treat cognitive impairments, neurodegenerative disorders (including Alzheimer's disease and ALS), and to support central nervous system functions.
Biotechnology and Cell Culture Media: Serves as a crucial nutrient in growth media for mammalian cell cultivation, which is used in the manufacturing of monoclonal antibodies, vaccines, and recombinant proteins.
Pharmaceutical Formulation & Supplements: Incorporated into the formulations of complex nootropic supplements, vitamin-mineral complexes, and specialized products aimed at optimizing brain metabolism and immune support.
Key Advantages
Pharmaceutical Purity (USP/EP/JP): Strictly complies with the world's leading pharmacopoeias. Minimal levels of impurities, heavy metals, and endotoxins guarantee safety of use in injectable dosage forms.
High Bioavailability: The L-isomer of this amino acid possesses 100% optical purity, ensuring immediate integration into metabolic processes without putting an extra load on enzymatic systems.
Stability in Solutions: Demonstrates excellent physicochemical stability when mixed with other amino acids and carbohydrates, remaining completely soluble without forming precipitates during sterilization.
Safety and GMP Compliance: Manufactured under strict GMP conditions, free from animal-derived components (BSE/TSE-free), hypoallergenic, and completely safe for sterile pharmaceutical production.
