Quality Control

Our (1S)-1-(3-Thienyl)Ethylamine is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC, to ensure compliance with exacting standards for research and development. Certificates of Analysis (COA) detailing identity, purity, and enantiomeric excess are provided and available upon request.

Storage

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