Quality Control

Our m-Tolylurea is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure high purity, consistency, and traceability. We provide detailed Certificates of Analysis (COA) with each shipment, which include data from tests such as HPLC for assay, identification by IR spectroscopy, and residual solvent analysis. Our quality commitment ensures the material meets the stringent requirements for use in pharmaceutical and fine chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and stability. Keep away from incompatible materials such as strong oxidizing agents.
