Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2014-2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: description based on visual inspection
Qualifier:
according to
Guideline:
other: In numerous guideline studies (e.g. for the determination of melting point, explosive properties) the physical state of 2,2'-[Azobis (1-methylethylidene)] bis [4,5-dihydro-1H-imidazole] dihydrochloride is described.
Deviations:
not applicable
Principles of method if other than guideline:
visual inspection of the test item;
GLP compliance:
not specified
Specific details on test material used for the study:
test samples of different production dates
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid
Colour:
slightly yellow
Odour:
faint
Substance type:
organic
Conclusions:
2,2'-[Azobis (1-methylethylidene)] bis [4,5-dihydro-1H-imidazole] dihydrochloride is described as a solid consisting of slightly yellow flakes. Furthermore the substance does not fulfill the criteria for gases or liquids according to Annex I, Part 1, 1.0 definitions of CLP Regulation, and therefore is considered as solid substance at room temperature.
