Quality Control

Our n-Propylphosphinothioic Dichloride is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity suitable for sensitive synthetic applications. Each lot is analyzed using advanced techniques including GC, NMR, and titration to verify identity and assay. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases and oxidizing agents.
