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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Conclusions:
- 2,2-Dimethylpropane-1,3-diyl dibenzoate is stable, because it shows no self-reactive or self-heating properties, there are no exothermic reactions up to >300 °C and it is not corrosive to metals.
- Executive summary:
2,2-Dimethylpropane-1,3-diyl dibenzoate is stable, because it shows no self-reactive (DTA) or self-heating (UN N.4) properties, there are no exothermic reactions up to > 300 °C (distillation method) and it is not corrosive to metals (UN 37.4).
Reference
SELF REACTIVE SUBSTANCE (CLP 2.8)
Results of trial 1 and trial 2:
- Trial 1 (26.9 mg): At a heating rate of 3 K/min, an exothermic reaction started at 215 °C with a heat release of about 13 kJ/kg
- Trial 2 (28.1 mg): At a heating rate of 3 K/min, no exothermic reaction could be measured under Argon-Atmosphere. The first exothermic reaction (trial 1) was an oxidizing reaction with the residual oxygen in the glass container. It disappears under argon. Based on the heat of decomposition and onset-temperature it is expected that SADT is > 75 °C.
CORROSIVE TO METALS (CLP 2.16)
The structural formula of 2,2-dimethylpropane-1,3-diyl dibenzoate shows no chemical groups in the molecule, that causes a corrosivity to metals and, thus, it can be concluded that 2,2-dimethylpropane-1,3-diyl dibenzoate is not corrosive to metals in the sense of the test guideline UN C.1 which is cited in GHS chapter 2.16.
Description of key information
2,2-Dimethylpropane-1,3-diyl dibenzoate is stable, because it shows no self-reactive or self-heating properties, there are no exothermic reactions up to >300 °C and it is not corrosive to metals.
Additional information
Justification for classification or non-classification
2,2-Dimethylpropane-1,3-diyl dibenzoate does not need to be classified, because it is stable and shows no corrosive properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
