Quality Control

Our [2-(Isopropylideneamino)Ethyl]Phosphonic Acid Bis(Trimethylsilyl) Ester is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including NMR, HPLC, and GC analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request 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.
