Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The estimated half-life at 25°C of the test material at pH 3, 7 and 11 was 58 minutes, 92 days and 16 days respectively.
Key value for chemical safety assessment
Additional information
A study on the hydrolysis of the test substance NBPT was conducted by Skinner and McKemie (1996) according to the EPA-guideline OTS 796.3500. The study was conducted in compliance with GLP requirements. In the test the hydrolysis of NBPT was investigated in two phases under different conditions. The resulting dissipation half-lives of the parent compound were 58 min (at pH 3), 92 d (at pH 7) and 16 d (at pH 11) at 25 °C, respectively.
In a supplement to the hydrolysis study, the major hydrolysis products were identified as N-(n-butyl) thiophosphoric diamide and butylamine by HPLC.
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.
