Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
2-nitropropane has been determined not to have explosive properties.
Key value for chemical safety assessment
- Explosiveness:
- non explosive
Additional information
We have evaluated the explosive properties of 2 -nitropropane according to the methodology described in the guidance document published by ECHA: first step was to examine the molecular structure of this substance and checked for the presence of groups associated with explosive properties. This yields the presence of the Nitro group. If such a group is present, we cannot waive the testing of explosive properties and the Oxygen balance (OB) is calculated. For 2 -nitropropane, the OB is -135. If the OB is less than -200, testing for explosive properties cannot be waived. Another possibility for waiving testing can be found if the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is above 500 °C. An expert in reactive chemistry within our company gave us the advice to perform the explosivity testing since he doubted that this possibility for waiving could bring a conclusion. Therefore, we asked HARLAN Laboratories to perform the explosiveness tests on this compound.
Justification for classification or non-classification
The explosivity tests were negative, so the substance is considered to be non 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).
