Quality Control

Our Urea, N,N'-Bis(3-Hydroxypropyl)- is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and high purity, meeting the specifications required for industrial and specialty chemical applications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment and is available upon request.

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.
