Quality Control

Our Bis(Phenylethynyl)Dimethylsilane undergoes rigorous quality testing to ensure compliance with industry standards. We employ analytical techniques including NMR, HPLC, and GC to verify identity, purity, and consistency. Certificates of Analysis (COA) are available upon request to support your research and quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
