Quality Control

Every batch of Dif-3 (CAS 113411-17-9) is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards, and comprehensive analytical testing is performed to verify identity, purity, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and product consistency for our global B2B clients.

Storage

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