Quality Control

Our 2,4-Diaminophenol Sulfate is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere for long-term stability and to minimize exposure to air and moisture.
