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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Stability
Phototransformation in air
This is not a standard information requirement for a registration under the REACH Regulation.
Hydrolysis
According to Annex VIII (Paragraph 9.2.2, Column 2) of the REACh regulation 1907/2006 a test on hydrolysis does not need to be conducted if the substance is readily biodegradable or highly insoluble in water. In addition alcohols are generally resistant to aqueous environmental hydrolysis. Therefore, 3 -methylbutan-1-ol is not expected to hydrolyze in the environment.
Phototransformation in water
This is not a standard information requirement for a registration under the REACH Regulation.
Phototransformation in soil
This is not a standard information requirement for a registration under the REACH Regulation.
Biodegradation
Biodegradation in water: screening test:
The ready biodegradability of the test substance itself was examined according to the OECD 301 F (Ready Biodegradability: Manometric Respirometric Test). The test substance was degraded 84 % in 27 days and the 10 days window criteria was fulfilled. The test substance was found to be readily-biodegradable under test conditions. The ready biodegradability of the test item was further assessed using a read-across category approach based on grouping of substances. The surrogate test substances were found to be readily biodegradable and a weight of evidence approach was applied.
Biodegradation in water and sediment
The substance is considered as readily biodegradable. Therefore, no further testing on biodegradation is required according to Annex IX (Paragraph 9.2.1, Column 2) of the REACh regulation 1907/2006.
Biodegradation in soil
The substance is considered as readily biodegradable. Therefore, no further testing on biodegradation is required according to Annex IX (Paragraph 9.2.1, Column 2) of the REACh regulation 1907/2006.
Bioaccumulation
Bioaccumulation: aquatic/sediment
Significant accumulation of the test substance in organisms is not to be expected. For 3 -methylbutan-1-ol was determined a log Kow= 1.35 (at pH ca. 6.5 and room temperature).
Bioaccumulation terrestrial
Data on terrestrial bioaccumulation in soil are not required for REACh registration.
Transport and distribution
Adsorption/Desorption
In accordance with Column 2 of REACH Annex VIII, the study need not be conducted if the substance has a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient), or the substance and its relevant degradation products decompose rapidly. The substance has a log Kow < 3 and is considered to be readily biodegradable.Testing is therefore not required.
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.
