Quality Control

Our o-Ethylisourea Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of our global B2B clients. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance.

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 stability and performance.
