Quality Control

Our D5Sics is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including chromatography (GC/HPLC) and spectroscopy (NMR, IR). A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in opaque packaging or amber glass.
