Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The maximum burning rate of test mixture is 1,89 mm/sec.
Key value for chemical safety assessment
Additional information
Valerophenone, which is tested according to EU A.17 Guideline, appeared to possess oxidizing properties as its maximum burning rate is higher than the maximum burning rate of the reference mixtures.
The classification, as oxidising substance, was not adopted at EU level (harmonised classification); therefore, the substance is not considered as oxidizer.
Justification for classification or non-classification
Several issues should be considered in order to evaluate the suitable classification of the substance:
- based on chemical structure, the CLP Regulation Annex I exclude that the substance may possess oxidising properties because it states that: "for organic substances or mixtures the classification procedure for this class shall not apply if:
(a) the substance or mixture does not contain oxygen, fluorine or chlorine; or
(b) the substance or mixture contains oxygen, fluorine or chlorine and these elements are chemically bonded only to carbon or hydrogen".
The 5-methoxy-4'-(trifluoromethyl)valerophenone has three fluorine atoms bounded only to carbon.
- Further, data available cannot be adopted for classifying the substance in accordance with the Regulation (EC) 1272/2008, because the data and the Regulation criteria are dissimilar.
- in order to comply with the Regulation 67/548/EEC, the substance classification as O, R8 and N, R51/53 was proposed. The European Community did not adopt the classification proposal and it evaluated the substance as N, R51/53 only (Regulation (EC) 1272/2008 Annex VI).
At the present, based on the actual knowledge and considering the issues above reported, the data are evaluated as inconclusive in order to classify the substance for oxidising properties in accordance with Directive 67/548/EEC and to Regulation (EC) 1272/2008.
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.
