Quality Control

Our o-Methylisourea Sulfate is produced under a rigorous quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay and impurity profiles. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed after opening to prevent degradation and moisture absorption.
