Quality Control

Our Phenol, 3,4-Diamino- is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous in-house specifications, which typically include identity confirmation, assay, and impurity profile analysis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic 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.
