Quality Control

Our D-Erythro-Penturonic Acid, 4-Deoxy-3-o-Methyl-, γ-Lactone (9Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. All batches undergo comprehensive analytical testing, including HPLC for purity, chiral analysis to confirm stereochemical integrity, and spectroscopic identification (NMR, IR, MS). A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profile is provided with each shipment to support your quality assurance and regulatory documentation needs.

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 in a dry environment to prevent degradation or clumping. For long-term storage, consider using desiccants.
