Quality Control

Our production of 1,1,3,5-Tetrakis(Trimethylsilyl)-1,2-Pentadien-4-Yne adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including NMR (¹H, ¹³C, ²⁹Si), GC-MS, and FTIR to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory needs.

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.
