Arginine Hydrochloride is the hydrochloride salt of the amino acid L-arginine, a conditionally essential amino acid involved in various physiological functions. It serves as a precursor to nitric oxide (NO), playing a vital role in vasodilation, immune function, wound healing, and urea cycle metabolism.
It is commonly used in:
∙ Parenteral nutrition formulations
∙ Metabolic alkalosis correction
∙ Ammonia detoxification in urea cycle disorders
∙ As a supplement in sports nutrition and cardiovascular support

As a naturally derived or synthetically produced amino acid salt, impurities in arginine hydrochloride can arise from fermentation, chemical synthesis, or degradation during storage. These must comply with ICH Q3A/B, USP, and EP standards to ensure safety in medical and nutritional applications.

It is used in parenteral nutrition, treatment of metabolic alkalosis, urea cycle disorders, and nutritional supplementation to support cardiovascular and immune function.
Arginine serves as a precursor for nitric oxide, a vasodilator, and is involved in protein synthesis, ammonia detoxification, and wound repair.
Yes, it is often used in balanced amino acid solutions, but its interaction with lysine and aspartic acid should be monitored to avoid competitive absorption.
It is stable under dry, cool conditions, but is hygroscopic and may degrade in the presence of moisture and heat. It should be stored in airtight, moisture-resistant containers.
