Administrative data

Endpoint:
acute toxicity: oral
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
A reliable secondary source, summaring FEB pharmaco-toxicological properties, was used. However, the primary sources were not revisited in order to verify their contents; for this reason reliability score 2 was used. The used secondary source has been updated on September, 2013; therefore it covers the most updated literature on the substance.
