Quality Control

Our 4-Oh-E1-1-N7Gua is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (NMR, MS), to ensure it meets the stringent requirements for research and development applications. A detailed Certificate of Analysis (COA) 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 place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under appropriate conditions to maintain stability.
