Quality Control

Our 2,3,4-Tri-o-Acetyl-α-D-Arabinopyranosyl Bromide is manufactured under strict quality systems to ensure batch-to-batch consistency and high chemical purity suitable for advanced synthetic applications. Each lot undergoes comprehensive analytical characterization including NMR, HPLC, and optical rotation to confirm identity, purity, and stereochemical integrity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry 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 decomposition.
