Quality Control

Every batch of our organotin compounds is produced under strict quality management protocols. We employ advanced analytical techniques including HPLC, GC, NMR, and ICP-MS to ensure high purity, precise composition, and batch-to-batch consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
