Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Becker et al. provide a well documented experimental study on the reaction of TDA with hydroxyl radicals under simulated atmospheric conditions.
The rate constants for the indirect photolysis of 2,4-TDA and 2,6-TDA were 1.9x10(-10)cm(3)/(molecule*sec) and 1.0x10(-10)cm(3)/(molecule*sec) respectively.
Key value for chemical safety assessment
Additional information
For the indirect photolysis of TDA, a tropospheric half-life time of <=2 h and 1h for the 2,6 and 2,4-isomers respectively was calculated assuming a tropospheric hydroxyl radical concentration of 1x106/ml.
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.
