Quality Control

Our (2-Mercaptoethyl)-Guanidine Sulfate is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, IR for identification, and titration for assay confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong oxidizing agents.
