Any other information on results incl. tables

1. The determination of the thermal stability of the test substance by DSC (Differential Scanning Calorimetry) showed that between 30°C and 400°C the exothermal decomposition energy is about -28.5 kJ/kg and therefore well below the limit of -500 kJ/kg needed for exclusion given in the Regulation (EC) No 1272/2008 (CLP) of the European Parliament and of the Council of 16 December 2008 on classification, labelling and packaging of substances and mixtures, Chapter 2.1.4.3. (c).

2. According to the chemical structure and the list of reactive groups that could have explosive properties (Bretherick’s Handbook of Reactive Chemical Hazards, Butterworths, 4th edition) it can be excluded that 2-Fluoro-5-(methylsulfonyl) Benzoic Acid has explosive properties.

Executive summary:

As stated in the reference (Commission Regulation (EC) No 440/2008, Annex A.14, § 1.1) “the tests need not to be performed when available thermodynamic information (e.g. heat of formation, heat of decomposition) and/or absence of certain reactive groups in the structural formula establishes beyond reasonable doubt that the substance is incapable of rapid decomposition with evolution of gases or release of heat (i.e. the material does not present any risk of explosion).”
