Quality Control

Our 2-Mercaptoethylguanidine is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR for identification, and Karl Fischer titration for moisture content, to ensure it meets exacting standards. A detailed Certificate of Analysis (COA) is provided with each shipment to guarantee traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at 2-8°C. Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed after each use to minimize exposure to moisture and air.
