Quality Control

Our production of this advanced intermediate adheres to strict quality management systems. Every batch undergoes comprehensive analytical characterization, including HPLC, NMR, and MS, to ensure structural identity and purity. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with client specifications. We support development projects with cGMP-compliant manufacturing options upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants.
