Quality Control

Our H-Arg-Glu-Oh is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and residual solvent screening, to meet the stringent requirements of research and cGMP-guided synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under dry, inert conditions to maintain stability and purity. For long-term storage, consider desiccated conditions at -20°C.
