Quality Control

Our production of this high-purity specialty chemical adheres to stringent quality protocols. Every batch undergoes comprehensive analytical characterization, including NMR (¹H, ¹³C, ²⁹Si), HPLC, and GC analysis, to confirm structural identity and purity. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting critical specifications. We are committed to consistent quality and supply reliability to support your critical research and development projects.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat and incompatible materials.
