Quality Control

Our Ethanethioic Acid, S-(2-Bromoethyl) Ester is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

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 presence of a bromoalkyl group and thioester moiety, it should be stored separately from strong bases, oxidizing agents, and reducing agents.
