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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 269-212-0 | CAS number: 68201-32-1
Melting point / freezing point
Administrative data
- Endpoint:
- melting point/freezing point
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification
- Remarks:
- Estimated by calculation using EPI Suite (v. 4.0) Quantitative Structure Activity Relationship (QSAR) computer model. EPI Suite has undergone detailed review by a panel of EPA’s independent Science Advisory Board (SAB) (http://www.epa.gov/sab/).
- Justification for type of information:
- EPI Suite has undergone detailed review by a panel of EPA’s independent Sc ience Advisory Board (SAB) (http://www.epa.gov/sab/).

Materials and methods

- Principles of method if other than guideline:
- General model to estimate the melting point (MP) of organic compounds. MP is estimated by two different methods; the first is an adaptation of the Joback group contribution method (see chapter 2 of "The Properties of Gases and Liquids" by R.C. Reid et al., NY: McGraw Hill, 1987) and the second is a method that correlates MP to BP (see chapter 2 of "Environmental Exposure From Chemicals" by W.B. Neely & G.E. Blau, CRC Press, 1985). The two MPs are then weighted according to chemical structure and magnitude of the difference between the two estimates to yield a preferred (suggested) melting point.
