Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Significant accumulation in organisms is not to be expected.

Key value for chemical safety assessment

BCF (aquatic species):
6.3 dimensionless

Additional information

In accordance with column 2 of REACH Annex IX, a study need not be conducted since the substance has a log Kow less or equal than 3. 1-Ethylpiperidine (CAS 766-09-6) has a log Kow of 1.89 (calculated; WoE, see ch. 4.7). The BCF value was calculated using EPISuite v4.11 SRC BCFBAF v3.01. The obtained BCF value was 8.2 L/kg ww (log BCF = 0.91). The key study is a read-across to the structurally similar substance 1 -methylpiperidine (CAS 626 -67 -5) according to OECD 305C determining a BCF of <6.3 at 1.0 mg/L in Cyprinus carpio (NITE, 2011). Therefore, significant accumulation in organisms is not to be expected.
