Quality Control

Our (Pentamethyldisilyl)Acetylene is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR, to ensure a minimum purity of 97% and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your R&D and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and highly volatile nature, it is recommended to handle under an inert atmosphere (e.g., nitrogen or argon) and store at temperatures between 2°C and 8°C for extended stability. Keep away from heat and open flame.
