Quality Control

Our Boroxin, Tris[[Tris(2-Methylpropyl)Stannyl]Oxy]- (9Ci) is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by titration or NMR, identification by FT-IR, and impurity profiling. Certificates of Analysis (COA) documenting all test results are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials.
