Quality Control

Our 2,4-Disulfobenzaldehyde-4'-Nitrophenylhydrazine, Disodium Salt is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your research or production requirements.

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, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials.
