Quality Control

Our 1-O,3-O:2-O,4-o-Dibenzylidene-D-Xylitol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling, to ensure it meets the high standards required for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data (HPLC, GC) are provided to guarantee reproducible quality and batch-to-batch consistency.

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.
