Quality Control

Every batch of 4-No2 14C6H4Op[S][Och3]2 is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the precise requirements for advanced synthetic applications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for all shipments. Our quality commitment supports compliance with ISO and cGMP standards where applicable for intermediate manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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. Keep away from heat and incompatible materials.
