Quality Control

Our 2-O,3-O:5-O,6-o-Bis(Isopropylidene)-α-D-Talofuranose is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and optical rotation measurement, to ensure high chemical purity and correct stereochemical identity. Certificates of Analysis (COA) with full traceability are available upon request, supporting compliance with cGMP and research-grade standards.

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 sealed to prevent degradation from atmospheric moisture.
