Quality Control

Our 3,3'-Dithiobis(Propionohydrazide) is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, melting point, and impurity profiles to guarantee consistency and reliability for your critical applications.

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 and propensity to be easily oxidized, it is recommended to handle the material under an inert atmosphere for long-term storage and to minimize exposure to air and humidity after opening the original container.
