Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

BCF = 3.16 L/kg wet-wt (based on QSAR; EPIWIN)

Key value for chemical safety assessment

BCF (aquatic species):
3.16 L/kg ww

Additional information

Monomethylamine possesses a measured logPow of -0.713 (BASF AG, 1988). Therefore, no accumulation in organisms is expected. According to REACH Annex VIII, no experimental data is necessary regarding bioaccumulation. For completeness, only a QSAR calculation was performed by EPIWIN (BCFBAF v3.00) resulting in a BCF of 3.16 L/Kg wet-wt (Chemservice S.A., 2010). This result refers to the regression-based estimate (traditional method) of BCFBAF.
