Quality Control

Our Dl-Arginine, Butanedioate (2:1), Tetrahydrate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for assay and purity, to ensure it meets stringent specifications suitable for pharmaceutical and research applications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and compliance with your quality protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and handling properties.
