Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The prediction was based on dataset comprised from the following descriptors: LD50
Estimation method: Taking average value from the 5 nearest neighbours
Domain logical expression:Result: In Domain

("a" and ("b" and "c" ) )

Domain logical expression index: "a"

Referential boundary: The target chemical should be classified as Esters (Acute toxicity) by US-EPA New Chemical Categories

Domain logical expression index: "b"

Parametric boundary:The target chemical should have a value of log Kow which is >= -0.698

Domain logical expression index: "c"

Parametric boundary:The target chemical should have a value of log Kow which is <= 2.84

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The acute oral median lethal dose (LD50) of ethyl 4,4,4-trifluoroacetoacetate in Rattus norvegicus in 6 hr study was estimated to be 2135.243 mg/kgbw.This value indicates that ethyl 4,4,4-trifluoroacetoacetate does not exhibits acute toxicity by the oral route.
Executive summary:

The acute oral median lethal dose (LD50) ofethyl 4,4,4-trifluoroacetoacetateinRattus norvegicusin 6 hr study was estimated to be2135.243 mg/kg/bw.Thus considering the CLP Criteria for classification of the substance, it is concluded that ethyl 4,4,4-trifluoroacetoacetatecould not exhibit acute toxicity in Rattus norvegicusby the oral route since the end point result indicates the value to be above 2000 mg/kg (which is the criteria for minimum classification)
