Quality Control

Our Dimethialium is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through a comprehensive suite of analytical techniques including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Recommended storage temperature is between 2°C and 8°C (refrigerated) to maintain optimal stability and prevent degradation. Keep container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to minimize contact with moisture and oxygen.
