Quality Control

Our Methyl-3,4-o-Isopropylidene-β-D-Arabinopyranoside is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and optical rotation measurement, to ensure high chemical and chiral purity consistent with research and production-grade standards. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to exclude moisture. For long-term storage, consider using a desiccant.
