Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No study has been conducted. A waiver argument is presented. 2,4-dichlorophenol does not possess any functional groups associated with oxidising properties which are active and thus capable of being released.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Annex VII (7.13) of Regulation (EC) No 1907/2006 states that the study on oxidising properties does not need to be conducted if :- — the substance is incapable of reacting exothermically with combustible materials, for example on the basis of the chemical structure (e.g. organic substances not containing oxygen or halogen atoms and these elements are not chemically bonded to nitrogen or oxygen, or inorganic substances not containing oxygen or halogen atoms). This is endorsed in the ECHA Guidance on Information requirements and chemical safety assessment, Chapter R.7a : Endpoint specific guidance in section R 7.1.13.3. In addition, this guidance document lists (non exhaustive) chemical groups associated with oxidising properties in Table R. 7. 1-29. 2,4-Dichlorophenol does contain the elements oxygen and chlorine but they are both bonded to carbon and thus are non active in that they are unlikely to be readily released. In addition, 2,4-Dichlorophenol does not contain any of the chemical functional groups associated with oxidising properties listed in Table Table R. 7. 1-29 of the ECHA Guidance on Information requirements and chemical safety assessment, Chapter R.7a : Endpoint specific guidance. Furthermore, 2,4-Dichlorophenol has a calculated oxygen balance of -117.79%. This indicates that the substance has an oxygen deficit and is unlikely to release oxygen.
Therefore, it is concluded that it is not justified, necessary or relevant to conduct an oxidising properties study on 2,4 -Dichlorophenol.
Justification for classification or non-classification
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.
