Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
With high probability acutely not toxic for fish.
Key value for chemical safety assessment
Additional information
Trimethylenediamine (CAS 109 -76 -2) was tested in a static acute toxicity test according to German Industrial Standard DIN 38412, part 15 with Leuciscus idus as test organism. The 96 -h LC50 was > 100 mg/L (not neutralized, nominal) and even > 464 mg/L after neutralization of the test solutions (neutralized, nominal; BASF AG, 1984; report no. 84/13). The test concentration were not analytically verified, but are assumed to be stable over the test period.
In a separate study by Brooke et al. (1984), the acute toxicity was tested with Pimephales promelas under flow-through conditions. The test procedure is similar to OECD 203. The test solutions were neutralised which resulted in a higher LC50. The 96 -h LC50 was 1190 mg/L (measured).
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.
