Quality Control

Our 2,5-Anhydro-3,4-o-(1,2-Ethanediyl)Mannitol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for research and process chemistry. Certificates of Analysis (COA) detailing purity (typically by HPLC or NMR), chiral purity, and other critical parameters are available upon request to support your quality assurance and regulatory needs.

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. Keep away from incompatible materials.
