Arginine hydrochloride

Arginine hydrochloride (CAS 1119-34-2 ), also known as L-Arginine HCL, is the hydrochloride salt form of the amino acid arginine, offering greater solubility and stability than the free base.

Under the brand name R-Gene 10, it has established clinical use as an intravenous diagnostic agent. Across industries, it functions as a pH buffer, humectant, and stabilizing agent in various formulations.

In injectable and oral pharmaceutical formulations, it stabilizes proteins and peptides while buffering pH in sensitive drug products. Nutritional supplement manufacturers use it to produce high-concentration powders.

It is frequently used in tablets and functional beverages where solubility is a critical processing requirement. In personal care, it conditions and moisturizes skin and hair formulations effectively.

This is particularly true in rinse-off and leave-on products targeting hydration. Food and clinical nutrition producers incorporate it into medical foods and enteral nutrition products for precise delivery.

Arginine hydrochloride is supplied as a white crystalline powder. It is available in USP , BP , and Ph. Eur. grades for pharmaceutical and clinical applications.

It is also available in food-grade specifications compliant with FCC standards. Bulk quantities are standard for industrial buyers, with smaller quantities available for R&D and quality testing.
