Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and spectral identification are provided with each shipment to guarantee traceability and performance reliability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed after each use to prevent degradation due to moisture absorption. Keep away from heat sources and incompatible materials.
