Reference
Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Remarks:
Data can be obtained from a reliable study report e.g. melting/freezing point study.
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
according to guideline
Guideline:
other: OECD 102/ 103, DSC
Qualifier:
according to guideline
Guideline:
other: TOS2004109
Version / remarks:
internal SOP (Standard Operation Procedure)
Principles of method if other than guideline:
Physical state of the substance is deduced from melting point study (Hesse, 2017). The appearance and colour is based on visual inspection. The odor was determined by means of an odour test (Certificate of Analysis).
GLP compliance:
yes
Physical state at 20°C and 1013 hPa:
solid
Form:
solid: particulate/powder
Colour:
Fine brown powder with an occasionally lump.
Odour:
other: Distinctive
Substance type:
organic
Conclusions:
Fine brown powder with an occasionally lump.
Distinctive odour.
