Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

explosive properties of explosives
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
Justification for type of information:
The structure of dicopper chloride trihydroxide 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.

Based on the chemical structure of the test item the result for the explosive properties has been predicted negative.

In addition, explosive hazards can occur if the exothermic energy of combustion is very high (>500J/g) and rapid. The substance does not decompose in a rapid energetic fashion. DSC data obtained for melting point determination show endothermic events only. This supports the conclusion that dicopper chloride trihydroxide is not likely to possess explosive properties.
