Quality Control

Our Diethynyl-Dimethyl-Germane is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay (by GC or NMR), identity confirmation (IR, NMR), and impurity profiling. Our quality commitment supports research and development requiring high-purity, reliable organometallic precursors.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at recommended temperatures between 2°C and 8°C to maintain stability and prevent decomposition. The container should be kept in a cool, dry, well-ventilated area, away from sources of heat, ignition, and incompatible materials.
