Quality Control

Our Ethyl Dl-Leucinate Hydrochloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and residual solvent screening, to ensure it meets stringent specifications for pharmaceutical and research applications. Certificates of Analysis (COA) detailing all test results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
