Quality Control

Our 1-(Guan-1-Yl)-2-(Cystein-S-Yl)Ethane is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification by spectroscopic methods (IR, NMR), purity assessment by HPLC, and specific tests for related substances. A Certificate of Analysis (COA) detailing all specifications and results is provided with every shipment to ensure traceability and compliance with your research or production standards.

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 sensitivity to oxidation, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended. Keep the container tightly sealed in a dry environment to minimize exposure to moisture.
