Quality Control

Our Tetracyclopropylgermane is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR (¹H, ¹³C), GC-MS, and elemental analysis, to verify identity and purity. A detailed Certificate of Analysis (COA) documenting all test results is provided with every shipment. We support custom synthesis and purification to meet specific research or production-grade specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C to maximize stability. Due to its moisture-sensitive and easily oxidized nature, the container should be kept sealed and allowed to reach ambient temperature before opening to prevent condensation.
