Quality Control

Our 5-Chloro-5H-Dibenzarsenole is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles, typically determined by advanced analytical techniques including HPLC, GC, and NMR. We support cGMP and ISO compliant production for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from incompatible materials. Due to the nature of organoarsenic compounds, appropriate safety measures should be observed during handling and storage.
