Quality Control

Our Antimony(III) Methoxide is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay and impurity profiling, to ensure it meets the high-purity standards required for advanced material synthesis and research applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) and opened only in a controlled, dry environment to prevent decomposition. Recommended long-term storage temperature is 2-8°C.
