Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

No experimental or human data were located on toxicokinetics ofpenta-1,3-diene. The OECD review panel (OECD SIDS, 2005) assumes that penta-1,3-diene may be absorbed and to be metabolized like other diolefins (e.g. isoprene). Mice was predicted to metabolize penta-1,3-diene more efficiently than rat.

Given that this substance is used only in closed industrial systems as monomer/intermediate substance with no dispersive use, human exposure to this chemical (outside industrial premises) will be of minimal concern.
