Quality Control

Our Benzamide,N,N'-1,4-Phenylenebis[4-Amino- is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity, IR for identification, and loss on drying, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture.
