Quality Control

Our Silicic Acid Tetrakis(1,1-Dimethylpentyl) Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC and identity confirmation by FT-IR and NMR, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing all specifications are 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 after initial use to prevent moisture absorption, which can affect product quality.
