Quality Control

Our 5H-Oxireno[C]Benzofuran, Hexahydro-, [1As-(1A-α-,3A-Bta-,7As*)]- (9Ci) is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, identity confirmation by IR and NMR, and quantification of key impurities. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting compliance with agreed specifications.

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 each use to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
