Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A study with reliability 1 carried out on Chrionomus riparius with an 80:20 mixture of 2,4- and 2,6-TDA gave a 28d NOEC of 125 mg/kg (sediment dry weight, nominal concentration of 80/20 TDA). It may be expected that ortho-TDA will behave similarly. 2,4-TDA is a structural isomer of o-TDA, differing in the substitution pattern of the amine groups on the tolyl ring; having similar physical chemical properties; similar environmental fate; and similar health effects (acute toxicity and genotoxicity). As a result, data from 2,4 -TDA can be used for read across to 2,3- TDA.
Key value for chemical safety assessment
Additional information
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.
