Explosiveness
Administrative data
- Endpoint:
- explosive properties of explosives
- Study period:
- 4th December 2012 (study start) to 10th Jan 2013 (assessment phase completed)
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

- Test System
The prediction was undertaken using a procedure designed to be compatible with Method A14 Explosive Properties of Commission Regulation (EC) No 440/2008 of 30 May 2008.
Performance of the Prediction
The structure of the test item was assessed for chemical groups that imply explosive properties. Examples of such groups are C-C unsaturated, C-metal, N-metal, contiguous oxygen atoms, contiguous nitrogen atoms, N-halogens, O-halogens, N-O. Examples of these groups are given below.
Structural Features Examples
C-C unsaturated: Acetylenes, acetylides, 1,2 - dienes
C-metal, N-metal: Grignard reagents, organo-lithium compounds
Contiguous oxygen atoms: Peroxides, ozonides
Contiguous nitrogen atoms: Azides, aliphatic azo compounds, diazonium salts, hydrazines, sulphonyl hydrazides
N-halogens: Chloramines, fluoroamines
O-halogens: Chlorates, perchlorates, iodosyl compounds
N-O: Hydroxylamines, nitrates, nitro compounds, N oxides, 1,2-oxazoles
Full structural details are given in Bretherick’s Handbook of Reactive Chemical Hazards, 7th Edition, Academic Press, 2007.
Data Handling
If there are no structural alerts within the structure then the explosive properties can be predicted negative. - GLP compliance:
