Quality Control

Our 3-Phenoxypropylmethyldichlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay and impurity profiling by GC and/or NMR, to ensure consistency and high purity. A Certificate of Analysis (COA) detailing specific results is provided with every shipment to guarantee compliance with your technical requirements.

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) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
