Description of key information
The acute toxicity of the test substance 2-methylbutan-1-ol to Zebrafish (Danio rerio) was assessed according to OECD 203 under GLP conditions in a semi-static system (BASF SE, 17F0340/10E022, 2011). The 96 hour LC50 was determined to be nominal greater than 120 mg/L.

Additional information
The acute toxicity of the test substance 2-methylbutan-1-ol to Zebrafish (Danio rerio) was assessed according to OECD 203 under GLP conditions in a semi-static system (BASF SE, 17F0340/10E022, 2011). The nominal test concentration was 120 mg/L and the mean measured concentration of the test substance was determined to be 112 mg/L. The 96 hour LC50 was determined to be nominal greater than 120 mg/L.
In addition the short-term toxicity to fish of the other category members was assessed.
A publication is available describing the acute toxicity of the category member 1-pentanol to Zebrafish (Danio rerio) according to OECD Draft 1980 and ISO TC 147/SCS/WG3 under Non-GLP conditions over 96 hours of exposure and under static conditions. The 96 hour LC50 was determined to be 530 mg/L based on the nominal concentration.
Supplementary the acute toxicity of 3-methylbutan-1-ol (another category member) to Salmo gairdneri (new name: Oncorhynchus mykiss) was assessed according to OECD 203 under static conditions. The 96 hour LC50 was determined to be nominal 700 mg/L.
In conclusion the 96h-LC50 value of the test substance and of the read across category members was determined to be greater than 100 mg/L.
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.
