Quality Control

Our Hn-(Peg1-Ch2Ch2Cootbu)2 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and commercial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee batch-to-batch consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label. Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can compromise product stability. For long-term storage, consider storing under an inert atmosphere.
