Quality Control

Our 4-Amino-4,5-dihydro-6H-cyclopenta[b]thiophen-6-one hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for research and production. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and protected from humidity. Keep away from incompatible materials.
