Quality Control

Our 4,4'-Diaminobenzanilide is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling. Certificates of Analysis (COA) documenting purity, identity, and relevant specifications are provided with every shipment to support your quality assurance protocols.

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 and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
