Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The adsorption potential of 2 -methyl-N-(4-sulfamoylphenyl) prop-2-enamide (SPM-N) was investigated in a study by Brekelmans (2008). This test was conducted according to OECD Guideline 121, under GLP conditions. The test substance was introduced in an analytical column containing a cyanopropyl stationary phase with both polar and non-polar sites, allowing for interaction of polar and non-polar groups of the substance in the same way as in soil or sewage sludge. The retention time in the column was measured. In the chromatogram of the test substance solution, one large test substance peak and two smaller peaks were observed. The large peak was considered to derive from the major component. The resulting log Koc value of 1.71 at 35 °C (major component) indicates that SPM-N has a low adsorption potential to solid particles.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
