Quality Control

Our Zonyl(R) Fsk is manufactured under a stringent quality management system to ensure batch-to-batch consistency and reliability. While specific grades may vary, our products undergo rigorous analytical testing, including assay, impurity profiling, and physical property verification, to meet exacting customer and industry requirements. Certificates of Analysis (COA) documenting purity, identity, and key specifications are available for every batch upon request.

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). Keep away from strong acids, strong bases, and strong oxidizing agents. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
