Bronopol – results of testing and assessment in consideration of UN TDG classification
- Bronopol (2-Bromo-2-nitropropane-1,3-diol) is classified since many years as a substances related to self-reactive substances according to the international regulations on the transport of dangerous goods (UN 3241, Division 4.1, Packing Group III). Based on all new test results and according to the principles of the UN Recommendations, Bronopol is not an explosive according to UN TDG (Class 1) and GHS Chapter 2.1 and is also not a self-reactive substance (SADT > 75 °C). Listing of Bronopol under 2.4.2.4.2 (UN model regulations) appears not to be justified compared to Musk Xylene, Azodicarbonamide and Isosorbid-5-mononitrate.
