Quality Control

Our production of 1-Propanone, 2-Chloro-1-(2-Thienyl)- adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity for research applications. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We employ advanced analytical techniques including HPLC, GC, and NMR to verify specifications. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive chloroketone group, it should be stored separately from strong bases and reducing agents.
