Quality Control

Our Arsenous Acid Tris(Trimethylsilyl) Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including NMR (1H, 13C) and chromatographic methods, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research and development requirements.

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, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
