Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
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
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
other: The test is performed according to EC guideline with some small deviations. However, there is no information on purity of the substance.
Qualifier:
according to guideline
Guideline:
EU Method A.14 (Explosive properties)
Deviations:
yes
Remarks:
1)The weight of the falling hammer is 5 kg and dropped from 0.8 m, however, the energy applied is the same as guideline, 40 J or 40 Nm. 2) In contrast to the EC guideline aluminium foil is used to pack the substance. 3) Ten tests are performed.
GLP compliance:
not specified
Parameter:
other: More sensitive to shock than m-dinitrobenzene
Remarks on result:
negative (not further specified)
Remarks:
If all tests according to Lütolf method are negative, powder can be considered not shock sensitive as reference substance meta-dinitrobenzene is not shock sensitive in similar conditions (although not tested simultaneously in this study)

Results:-

-10 times negative, not shock sensitive (sensitivity > 39.2 Nm).

Conclusions:
The test substance is not shock sensitive.

Description of key information

There are no chemical groups present in the molecule which are associated with explosive properties (no tests performed, waiving).

A study of which the reliability was not assignable (K4, Janssen Pharmaceutica Process Safety Center, 2004) concluded that the test substance is not shock sensitive (sensitivity > 39.2 Nm) according to the LUTOLF method.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

T002478 does not need to be classified as explosive as based on the chemical structure T002478 does not contain any chemically instable or highly energetic groups that might lead to an explosion.
