Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Justification for classification or non-classification
The presence of the impurity formaldehyde (up to 0.999%) triggers a classification for the registered substance as a carcinogen Cat 1B (H350: May cause cancer).
Additional information
Carcinogenic potential of the main constituent 3-methylbut-3-en-1-ol (CAS 763 -32 -6).
No carcinogenicity data are available for 3-methylbut-3 -en-1-ol (Isoprenol).
Carcinogenic potential of the impurity formaldehyde (CAS 50-00-0).
The impurity formaldehyde is found to be present at concentrations up to 0.999% in the substance to be registered (3-methylbut-3 -en-1-ol; Isoprenol)).
Formaldehyde is listed in Annex VI to the CLP Regulation with the harmonized classification as a carcinogen Cat.1B (H350: May cause cancer).
Accordingly, the registered substance (3-methylbut-3 -en-1-ol or Isoprenol) needs to be classified as a carcinogen Cat.1B (H350: May cause cancer) due to the impurity formaldehyde.
For the alternative grade (without relevant levels of the impurity formaldehyde), no data are available warranting a classification of the registered substance (3-methylbut-3 -en-1-ol or Isoprenol) as a carcinogen.
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.
