Quality Control

Our Butanoic Acid, 2-Hydroxy-3-Oxo-, (2S)- (9Ci) is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment.

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.
