Quality Control

Our n-(Diphenylphosphinothioyl)-N'-Phenylthiourea is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods (NMR, IR) for structural confirmation, to ensure it meets the high standards required for research and synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

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 each use to prevent degradation. Keep away from incompatible materials.
