Quality Control

Our 2-(5-Chloro-Thiophen-2-Yl)-Ethylamine is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with each shipment, confirming compliance with customer specifications and relevant industry standards. Custom purity grades and analytical packages are 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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
