Quality Control

Our 4-Phenylbutylmethyldichlorosilane is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance requirements.

Storage

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