Quality Control

Every batch of 2-Amino-4-Chlorodiphenylsulfide is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Our comprehensive quality control includes identity confirmation, purity assay, and impurity profiling. A detailed Certificate of Analysis (COA) documenting all test results is provided with each shipment to guarantee traceability and consistency.

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 and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
