Quality Control

Our (S)-(-)-2-Guanidinoglutaric Acid S-Methylisothiourea Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity verification and impurity profiling, to ensure it meets the high standards required for research and development applications. Certificates of Analysis (COA) detailing purity, identity, and specific test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
