Quality Control

Our Phenol, 3,5-Diamino- is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC, GC, and spectroscopic methods, to meet precise customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each 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 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. Keep away from strong oxidizing agents.
