Quality Control

Every batch of (3-Amino-2-Thienyl)Acetate is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting key parameters such as purity (by HPLC), identity (by IR and NMR), and impurity profiles. Our quality commitment supports compliance in cGMP and ISO-guided environments.

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 after opening to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
