Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
acute toxicity: oral
Type of information:
(Q)SAR
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
Justification for type of information
1. SOFTWARE
OECD [Q]SAR Toolbox
2. MODEL (incl. version number)
QSAR Toolbox 3.4.0.17
Database version: 3.8.8/3.1.2
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
CAS: 73398-85-3
SMILES: CC(CCC1C(C)=CCCC1(C)C)C=O
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
Please see the attached OECD [Q]SAR Toolbox report.
5. APPLICABILITY DOMAIN
The prediction is based on 10 values within the range 0.771 - 2.01, log(1/mol/kg)
Prediction confidence = ± 0.228, log(1/mol/kg) (95.0%)
6. ADEQUACY OF THE RESULT
The LD50 prediction (5800 mg/kg) in rats is similar to the Klimisch 4 study where the LD50 was 9.1 ml/kg (7.0 - 11.8 ml/kg): Result in mg/kg : Density = 0.9165 g/cm3 at 20'C, thus LD50 = 9.1 ml x 0.9165g/cm3 = 8.34 g/kg
= 8340 mg/Kg.
