Quality Control

Our Pentanoic Acid, 3-Hydroxy-4-Oxo- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

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 tightly sealed after opening to prevent degradation from atmospheric moisture.
