Quality Control

Our production of 2-Chlorodihydro-1,3,2-Dithiaphosphole adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research and industrial use. Each lot is analyzed using advanced techniques including NMR, GC, and HPLC to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
