Quality Control

Our 5-Chloro-3-Nitro-o-Phenylenediamine is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR), to ensure it meets exacting specifications for use in sensitive applications like dye synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and consistent batch-to-batch quality.

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.
