Quality Control

Our 4-Chloro-6-Hydrazino-1,3-Benzenedisulfonamide 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 high-grade standards suitable for synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

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 sensitivity, the container should be kept under an inert atmosphere (e.g., nitrogen) to prevent oxidation and moisture absorption. Keep away from heat, sparks, and open flame.
