Description of key information
The rate of disappearance by abiotic degradation (hydrolysis) of N-(2-nitrophenyl)phosphoric triamide in aqueous solutions at pH 4, 7 and 9 was studied on the basis of OECD Guideline no. 111. The key study is GLP compliant and has Klimisch score 1.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 148.4 d
- at the temperature of:
- 25 °C
Additional information
N-(2-nitrophenyl)phosphoricacid triamide) did undergo hydrolysis at pH 4 (DT-50 of 28.5 hours) and pH 9 (DT-50 of 48.2 hours). A very slow hydrolytic reaction occurred at pH 7 (DT-50 of 148.4 days).
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).
