Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

no oxidising properties (EU A.17, test with reference substance barium nitrate)

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

On the basis of the chemical structure the substance 2-methyl-N-(4-sulfamoylphenyl) prop-2-enamide (SPM-N) is incapable of reacting exothermically with combustible materials. This conclusion is supported by the result of the test performed according to EU Method A.17 (reference substance: barium nitrate). In air atmosphere the maximum burning rate for the test substance was 0.89 mm/s (10/90, w/w test substance/cellulose mixture), which was significantly higher than the maximum burning rate for the reference substance (0.68 mm/s, 60/40 w/w reference substance/cellulose mixture). It was interpreted as a false positive result and the test was repeated in an inert test atmosphere (nitrogen with 9 - 10% oxygen). The test substance/cellulose mixture (10/90 w/w) could not be ignited under these conditions.

Justification for classification or non-classification

The available data on oxidising properties of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification: Based on the chemical structure the substance is not oxidising. The outcome of the test according to EU Method 17 (reference substance: barium nitrate) supports this conclusion.
