Description of key information
2-Methyl-p-phenylenediamine sulfate (Haarbraun) Koc measurec according OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)) was 0.076 at pH 3 and 17.3 at pH 6.
Key value for chemical safety assessment
- Koc at 20 °C:
- 17.3
Additional information
2-Methyl-p-phenylenediamine sulfate (Haarbraun) was measured according to OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)).
Dead time at pH 3= 3.067 +/- 0.013, at pH 6= 2.775 +/- 0.008, the validity critera were fullfilled.
According to the McCall classification scheme of soil mobility potential a Koc of 0.076 (pH 3) and of 17.3 (pH 6) would indicate a very high mobility for the test substance.
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.
