Quality Control

Our 1,3-Propanediamine, 2-Phenyl- is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to guarantee traceability and consistency.

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 tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality. Keep away from strong oxidizing agents.
