Quality Control

Our (Heptafluoroisopropoxy)Propylmethyldichlorosilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including assay and impurity profiling. A Certificate of Analysis (COA) detailing specific results for purity, identity, and other critical parameters is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
