Quality Control

Our Attophos is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for synthesis applications. Quality is verified through a comprehensive suite of analytical techniques including HPLC, GC, and NMR spectroscopy. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, identity, and impurity profiles 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 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 incompatible materials.
