Quality Control

Our 2-[3-(4-Aminobutylamino)Propylamino]Ethanethiol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and structural confirmation, to ensure it meets the high standards required for research and synthesis. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurities is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry place. 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. Keep away from strong oxidizing agents.
