Quality Control

Our 1,4-Dichloro-2,3-benzenediamine is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment and is available upon request.

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.
