Quality Control

Our 4,5,6,7-Tetrahydro-2-Amino-6-Butylthieno(2,3-C)Pyridine-3-Carboxylic Acid Ethyl Ester Hydrochloride is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed specifications are provided to guarantee compliance with your research and manufacturing requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 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.
