Quality Control

Every batch of Af 57 (CAS 96107-38-9) is manufactured under a strict quality management system. Our products undergo rigorous analytical testing, including chromatography and spectroscopy, to ensure they meet precise purity and consistency standards. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
