Quality Control

Our Zirconium(IV) tert-Butoxide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of advanced materials and electronics industries. A comprehensive Certificate of Analysis (COA) detailing purity, metal content, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (argon or nitrogen) to prevent decomposition.
