Quality Control

Our Guanidine Monohydrobromide is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is subjected to comprehensive analytical testing, including identification, assay, and impurity profile analysis. Certificates of Analysis (COA) detailing all test results are provided and can be tailored to meet specific customer or regulatory requirements, supporting applications in cGMP environments.

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 to prevent moisture absorption, which can affect product quality and handling properties.
