Quality Control

Our 3,4-Di-o-Acetyl-D-Arabinal is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and chiral purity analysis, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
