Quality Control

Our production of (S)-3-Aminodihydro-2(3H)-thiophenone adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including chiral purity analysis (HPLC), to ensure it meets the high standards required for research and synthesis applications. A detailed Certificate of Analysis (COA) specifying identity, purity, enantiomeric excess, and impurity profile is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 after opening to prevent degradation from atmospheric moisture.
