Quality Control

Our production of (1-Butyl-1-Methyl-4-Tributylstannanyl-But-3-Enyloxy)-Trimethyl-Silane adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Each lot is characterized using advanced analytical techniques including NMR (1H, 13C, 119Sn), GC-MS, and FT-IR to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

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 place. 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.
