Quality Control

Our 5-Chloro-2,3-Dihydro-2-Phenyl-1,3,2-Benzothiazaphosphole 2-Sulfide is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory needs.

Storage

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