Pharmaceutical Chemistry
L-Arginine Hydrochloride
Formula:
C₆H₁₅ClN₄O₂
GOST/CAS:
CAS 1119-34-2
L-Arginine Hydrochloride is the hydrochloride salt of the essential (conditionally essential) amino acid L-arginine, characterized by a high degree of purity and excellent water solubility. The product presents as a white crystalline powder or colorless crystals with a faint, characteristic odor. Due to its high bioavailability and stability, L-Arginine HCl serves as a key raw material component in the pharmaceutical, food, and cosmetic industries, as well as in the production of specialized sports nutrition and feed additives.
Applications
Pharmaceutical Manufacturing: Utilized as an Active Pharmaceutical Ingredient (API) for the synthesis of drugs that improve myocardial metabolism, hepatoprotectors, parenteral nutrition solutions, and detoxifying agents.
Supplements & Sports Nutrition: Serves as a core component in pre-workout complexes and supplements (nitric oxide boosters) aimed at enhancing muscle pump, endurance, and accelerating recovery.
Food Industry: Applied as a fortifying additive and functional ingredient in dietary food products and beverages.
Cosmeceuticals & Personal Care: Used in formulations for anti-aging cosmetics, creams designed to improve skin microcirculation, and restorative hair care products.
Key Advantages
High Bioavailability & Stability: The hydrochloride form (HCl) is significantly more stable than free-base L-arginine, dissolves faster in water, and is more readily absorbed by the body.
Stimulation of Nitric Oxide (NO) Synthesis: Effectively dilates blood vessels, improving blood flow and the transport of nutrients to tissues and organs.
High Purity Level: The product fully complies with strict international quality standards (USP/EP/BP), guaranteeing the absence of foreign impurities and ensuring safety in use.
Mild pH Profile: Unlike free-base arginine, which has a highly alkaline reaction, the hydrochloride form features a more neutral pH in solutions, simplifying the technological process of finished product manufacturing.
Storage & Transportation
- Store in dry, cool, light-protected, and well-ventilated warehouse premises in tightly sealed original packaging.
- Avoid exposure to direct sunlight, moisture, and high temperatures. The product is hygroscopic.
- Transportation is permissible by all types of covered transport in accordance with standard cargo regulations. The material is classified as non-hazardous for transport. Shelf life — 2-3 years (depending on the manufacturer).
