Quality Control

Our Tributyl(Phenylethenyl)Tin is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including NMR, GC, and elemental analysis, to verify identity and assay. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality parameters. We adhere to relevant industry standards for laboratory chemicals and can support custom purity requirements for specific R&D or process applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 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. Keep away from heat, sparks, and open flame.
