Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity. Our products undergo comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment. We can supply material compliant with research and custom synthesis grade specifications, with the capability to tailor purity to specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Allow the container to reach ambient temperature before opening to minimize moisture ingress and degradation.
