- Details on metabolites:
- CAS number CAS name SMILES Molecular Formula Blood brain barrier Oral absorption Skin permeability
64-19-7 Acetic acid CC(O)=O C2H4O2 Poor permeability Highly absorbed High skin permeability
75-07-0 Acetaldehyde CC=O C2H4O Poor permeability Highly absorbed High skin permeability
64-17-5 Ethanol CCO C2H6O Poor permeability Highly absorbed High skin permeability
1070-34-4 Butanedioic acid, 1-ethyl ester CCOC(=O)CCC(O)=O C6H10O4 Poor permeability Highly absorbed High skin permeability
110-15-6 Butanedioic acid OC(=O)CCC(O)=O C4H6O4 Poor permeability Moderately absorbed High skin permeability
Applicant's summary and conclusion
- Conclusions:
- The rat liver metabolic simulator of the (Q)SAR Toolbox v4.3.1 suggest 5 metabolites for diethyl succinate, having similar mechanistic profiles:
Blood brain barrier: Poor permeability
Oral absorption: Highly/moderately absorbed
Skin permeability: High skin permeability - Executive summary:
Diethyl succinate, as well as its metabolites, appears to be bioavailable.
