Quality Control

Our 1,4-Phenylenediamine Sulfate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, impurity profile, and physical characteristics to guarantee supply reliability and batch-to-batch consistency for your critical applications.

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 preservation and to minimize contact with air. Keep away from strong oxidizing agents.
