Quality Control

Our Dimethylbis(2,3,4,5-tetramethyl-2,4-cyclopentadien-1-yl)silane is produced under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including NMR (1H, 13C) and GC or HPLC analysis, to verify identity and purity against established specifications. Certificates of Analysis (COA) detailing all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, and open flame.
