Quality Control

Our Antimony(III) Tetrafluoroborate is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure consistency, purity, and compliance with relevant industry specifications. Certificates of Analysis (COA) detailing assay, impurity profiles, and physical characteristics 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 area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment. Keep away from incompatible materials such as strong bases and fluorides.
