Quality Control

Our 2,5-Diaminophenol 2Hcl is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical documentation, including Certificates of Analysis (COA) with detailed HPLC/GC profiles, to support your quality assurance and regulatory compliance needs. Our production adheres to cGMP principles where applicable.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
