Quality Control

Our Variamine Blue B Diazonium Salt is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is tested against stringent in-house specifications, which typically include assay (purity), identification, and impurity profile analysis. A Certificate of Analysis (COA) detailing the results is provided with every shipment to guarantee compliance with your technical requirements.

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 light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize decomposition. Keep away from heat, sparks, and open flames.
