Quality Control

Our St 679 is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopy, to verify identity, purity, and conformance to established specifications. A Certificate of Analysis (COA) documenting all critical quality attributes is provided with every shipment to ensure full traceability and support your regulatory compliance 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.
