Quality Control

Our production of 4,4'-Diazidostilbene Sulfonic Acid adheres to stringent internal quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques such as HPLC, NMR, and FTIR for identity confirmation and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and relevant physical data is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after the container has been opened.
