Quality Control

Our 2-Thiopheneacetyl Chloride, 3-Methyl-α-Oxo- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your research and development specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from strong bases and oxidizing agents.
