Quality Control

Our Pentamethyldisilane 97 is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including gas chromatography (GC) and NMR spectroscopy to verify identity and assay. A Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic (moisture-sensitive) nature, this product must be stored under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C. Keep away from heat, sparks, open flames, and oxidizing agents.
