Quality Control

Every batch of α-D-Xylo-Pentodialdo-1,4-Furanose,3-o-Ethyl-1,2-o-(1-Methylethylidene)-(9Ci) is manufactured and tested under a strict quality management system. Our products undergo rigorous analytical testing, including HPLC, NMR, and optical rotation measurement, to ensure identity, purity, and chiral integrity meet the high standards required for research and commercial synthesis. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed and desiccated when not in use to maintain stability and purity.
