Quality Control

Our D-Base CAS NO 50961-68-7 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assay and impurity profiling, to ensure it meets the stringent requirements for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) with detailed HPLC/GC data are provided to guarantee consistent quality and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a 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.
