Quality Control

Our S-2-(3-Methylaminopropylamino)Ethanethiol is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography and spectroscopic methods, to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specific results for purity, assay, and impurity profiles is provided with every shipment to guarantee it meets your research or production 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 area. Recommended storage temperature is 2-8°C for long-term stability. Due to its sensitivity to oxidation, containers should be kept sealed and purged with inert gas after each use.
