Quality Control

Our L-Arginine Hydrochloride is manufactured under a quality management system and undergoes rigorous analytical testing to ensure it meets the required specifications for identity, purity, and strength. We can supply material compliant with various pharmacopeial standards, including USP-NF and EP monographs, depending on the grade. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each batch to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
