Quality Control

Every batch of 2,6-Bis(Trimethyltin)-Dioctyl- is produced and tested under stringent quality management protocols. We ensure high purity and consistency through advanced analytical techniques including NMR, GC-MS, and ICP-OES for tin content and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific impurity limits is provided with each shipment to guarantee it meets your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. This compound is easily oxidized and moisture-sensitive; ensure containers are sealed immediately after use to prevent degradation.
