Quality Control

We supply Threo-Pentonic Acid, 2,5-Anhydro-3-Deoxy-, Methyl Ester (9Ci) in high-purity grades suitable for research and process development. Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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.
