Quality Control

Our 3,5-Dinitro-L-Tyrosine Sodium Salt 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 the stringent requirements of research and development applications. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee traceability, consistency, and reliability.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
