Endpoint summary
Administrative data
Key value for chemical safety assessment
Genetic toxicity in vitro
Description of key information
3-amino-2-chloro-6-methylphenol was not mutagenic in an Amestest according to OECD guideline 471 in strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 with and without metabolic activation.
In a mouse lymphoma assay in cell line L5178Y (tk+/--locus) according to OECD guideline 476,the test substance did not induce gene mutations with and without metabolic activation.
In an in vitro chromosome aberration test in Chinese hamster V79 cells according to OECD guideline 473,the test substance induced structural chromosome aberrations both in the presence and absence of metabolic activation.
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (positive)
Genetic toxicity in vivo
Description of key information
3-amino-2-chloro-6-methylphenol was tested in an in vivo micronucleus study on NMRI mice according to OECD guideline 474.
Dose levels were selected according to toxicity observed in a pre-experiment.
In the main study,the analysis of blood samples of the males treated with the highest dose of 400 mg/kg bw showed that the test item could be quantified in the blood confirming its bioavailability.
Under the test conditions 3-amino-2-chloro-6-methylphenol was not clastogenic and/or aneugenic in the bone marrow cells of mice.
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (negative)
