Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and purity. Our products undergo comprehensive analytical testing, including GC, HPLC, and NMR, to verify identity and assay. A Certificate of Analysis (COA) detailing purity and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is 2-8°C for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and potential moisture absorption.
