Quality Control

Our Nntetramethyleneurea is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification by FT-IR, purity assay by HPLC, and control of key impurities. A Certificate of Analysis (COA) detailing all test results is provided with every shipment 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 a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial opening to prevent moisture absorption, which can affect product stability and performance.
