Quality Control

Our 2-Methylpropene-1-Tributylstannane is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR (1H, 13C, 119Sn) and chromatographic methods (GC, HPLC), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to relevant industry standards and can support development projects requiring specific analytical data packages.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation and light, prolonged exposure to air or direct light should be avoided. Keep away from heat, sparks, and open flame.
