Quality Control

Our Tetrakis(Methylphenyl) Orthosilicate is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise customer specifications and consistent high-quality standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and stability. Keep away from incompatible materials such as strong acids and bases.
