Quality Control

Every batch of D-Erythro-Pent-4-Enitol, 1,5-Anhydro-4-Deoxy-2,3-o-(1-Methylethylidene)- (9Ci) is produced and tested under a strict quality management system. We ensure high purity and batch-to-batch consistency through comprehensive analytical techniques including HPLC, GC, NMR, and chiral analysis. A detailed Certificate of Analysis (COA) specifying identity, purity, and impurity profiles is provided with each shipment to support your regulatory and R&D requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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 by atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
