Quality Control

Our 3,4-Dichloroisothiazole-5-Carboxylic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to its carboxylic acid functionality and halogenated structure, it should be stored separately from strong bases, oxidizing agents, and reducing agents.
