Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 freezing point of the substance is estimated to be -10.7°C based on read-across from a suitable structural analogue.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -10.7 °C
Additional information
The freezing point an appropriate structural analogue, 3-(4-tert-butylphenyl)propionaldehyde (tradename Bourgeonal) was measured according to OECD Guideline No. 102, EU Method A.1 and EPA OPPTS 830.7200 (method of the freezing temperature). Under the conditions of the test, the freezing point of the test material was determined to be -10.7ºC (262.45 K).
The study was performed in compliance with GLP and in accordance with recognised standardised guidelines and was assigned a reliability score of 2 in line with the principles defined in Klimisch et al (1997) as the study was performed on a structural analogue of the substance. Due to the structural similarities between the two substances, it was considered appropriate to use data from the source substance to represent the target substance (for further details see read-across justification document, attached in section 13).
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.
