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.

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).
