Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The boiling point of Isopropylmagnesium chloride ca. 20% in THF was 62.4°C under 89.98kPa atmospheric pressure. As the atmospheric pressure of the measured boiling point was not in the range of +/- 5 kPa to the standard atmospheric pressure (101.325 kPa) the calculation to normal boiling point according to the equation of Sidney Young is not feasible.
The density of Isopropylmagnesium chloride ca. 20% in Tetrahydrofuran was determined to be 0.97 g/cm3, relative Density (D20;4) = 0.97.
The flash point of the test item is -27.0 °C under atmospheric conditions (1013.3 hPa).
The auto-ignition temperature of the test item according to the auto-ignition test conditions in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.15. is 240 °C.
The heat of decomposition was determined to a maximum energy of 792 J/g. Due to an energy release above 500 J/g further tests are necessary to classify the test item as explosive according to class 1 of the Recommendations on the Transport of Dangerous Goods and chapter 2.1 according to GHS (CLP) or to exclude it from the aforementioned classifications.
Due to the results from the UN-tests 1(b) (effect of heating under confinement; Koenen-test), 1(c) (effect of ignition under confinement; Time-pressure-test) and F.3 (Trauzl-test; substitute test for 1(a) (propagation of detonation) of the „UN Recommendations on Transport of Dangerous Goods - Manual of Test and Criteria“ on the Grignard reagent methylmagnesium chloride it can be concluded that the Grignard reagent isopropylmagnesium chloride is also not explosive.
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.
