Quality Control

Our 7-(Chloromethyl)-2-Methylbenzo[B]Thiophene is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
