Quality Control

Our Chloro-Dioctyl-Tin, Dioctyltin, Methanol, Hydrate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for tin content, chloride content, and methanol content. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing results for identity, assay, and purity. Our quality protocols are designed to ensure batch-to-batch consistency and reliability for industrial processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent exposure to atmospheric moisture, which can compromise product integrity. Keep away from heat sources and incompatible materials.
