As an accredited Thioacetic Acid factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Brown glass bottle with secure cap, labeled "Thioacetic Acid, 99%," 500 mL, hazard warnings and handling precautions clearly displayed. |
| Shipping | Thioacetic acid should be shipped in tightly sealed containers made of compatible materials, stored upright, and clearly labeled. It must be handled as a corrosive, flammable liquid. Ship in accordance with relevant transport regulations (UN 2966, Class 8, Packing Group II), protecting from heat, sparks, and incompatible substances during transit. |
| Storage | Thioacetic acid should be stored in a tightly sealed container under an inert atmosphere, such as nitrogen, to prevent oxidation. Keep it in a cool, dry, and well-ventilated area away from moisture, heat sources, and incompatible substances such as oxidizing agents. Due to its unpleasant odor and corrosive nature, store in a chemical fume hood and handle with appropriate protective equipment. |
