Pharmaceutical Chemistry
Methionine
Formula:
C₅H₁₁NO₂S
GOST/CAS:
CAS 59-51-8 (DL-метионин) / 63-68-3 (L-метионин)
Methionine Pharm Grade (L-Methionine / DL-Methionine of pharmaceutical quality) is an essential sulfur-containing amino acid that serves as a critical building block for the synthesis of proteins, choline, lecithin, and other biologically active compounds. The product is a white or almost white crystalline powder with a characteristic odor, easily soluble in water. Due to its pronounced hepatoprotective, metabolic, and antioxidant properties, methionine is an indispensable baseline raw material in the manufacture of pharmaceuticals, dietary supplements (nutraceuticals), and specialized clinical nutrition products.
Applications
Hepatoprotector Production: Used as an Active Pharmaceutical Ingredient (API) for monotherapy and combined drug formulations designed to treat and prevent liver disorders (cirrhosis, fatty degeneration, hepatitis, and toxic liver injuries).
General Metabolic Pharmaceuticals: Incorporated into complex metabolic agents, drugs targeting protein deficiency and atherosclerosis, as well as formulations aimed at stimulating recovery processes following severe illnesses or surgeries.
Dietary Supplements & Vitamin Complexes: Used in premium formulations of dietary supplements to support metabolism, facilitate systemic detoxification, improve the condition of skin, hair, and nails, and enrich specialized sports nutrition lines.
Clinical & Parenteral Nutrition: Formulated as an essential component in specialized amino acid intravenous infusion solutions and clinical diets for enteral feeding.
Key Advantages
High Biological Activity: Effectively regulates nitrogen balance, actively participates in methylation and transsulfuration pathways, ensuring a rapid and targeted therapeutic response.
Premium Purity & Compliance: Pharmaceutical grade quality guarantees strict compliance with leading global pharmacopoeias (Ph. Eur., USP, BP), ensuring negligible impurity profiles and heavy metal levels.
Hepatoprotective & Detox Effect: Promotes the mobilization and clearance of excess lipids from liver tissue, accelerates hepatocyte regeneration, and chemically binds toxic metabolic breakdown products.
Exceptional Processability: Easily dosed, blended, and homogenized with other dry excipients, maintaining excellent stability across various dosage forms such as tablets, capsules, and sachets.
Storage & Transportation
- Store in dry, cool, and well-ventilated warehouses, shielded from direct light in tightly closed original packaging, away from heat sources and strong oxidizing agents.
- Recommended storage temperature: +5°C to +25°C with a relative atmospheric humidity not exceeding 70%.
