Quality Control

Our 2-Guanidinoethylphosphonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, impurity profile, and physical characteristics. We support customer audits and can provide material to meet specific research or cGMP starting material requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the container must be kept in a cool, dry place with minimal exposure to atmospheric humidity. Recommended storage temperature is 2-8°C for long-term stability. Allow the container to reach room temperature before opening to prevent moisture condensation.
