Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Carcinogenicity
Administrative data
Description of key information
Two carcinogenicity studies are available:
Stott WT, Yano BL, Beyer JE, Kropscott BE, Eddy SL (1991): 2 year study in rats: NOAEL (carcinogenicity): 1000 mg/kg bw/day (actual ingested) (male) and 1000 mg/kg bw/day (actual ingested) (female)
Bond DM, Crissman JW, Kropscott BE, Quast JF (1991): 2 year study in mice: NOEL (carcinogenicity): > 1000 mg/kg bw/day (actual ingested) (male/female)
Key value for chemical safety assessment
Carcinogenicity: via oral route
Endpoint conclusion
- Dose descriptor:
- NOAEL
- 1 000 mg/kg bw/day
Justification for classification or non-classification
With reference to the information available on this substance, no classification for carcinogenicity is required in accordance with Directive 67/548/EEC or Regulation (EC) No. 1272/2008.
Additional information
The key study was selected on the basis that it was performed on the most typical species (rat) used to address the carcinogenicity endpoint. The key study gives the same NOAEL as the supporting mouse study, and therefore the worst case is represented by the key study. In the key study, no treatment-related tumorigenic response was observed in either sex of rats administered Flumetsulam at dose levels of up to 1000 mg/kg bw/day.
The key study is a reliable EPA guideline study, performed to GLP standard.
No evidence of carcinogenicity was seen in either mice or rats.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
