Quality Control

Our Attophos is produced under a rigorous quality management system to ensure batch-to-batch consistency and high purity. Quality control includes comprehensive analytical testing such as HPLC, NMR, and GC-MS to verify identity and assay. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
