Reference
Endpoint:
appearance / physical state / colour
Type of information:
other: observation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: company data from Certificate of Analysis confirming the physical state, form and colour; this data is considered reliable and suitable for use.
Qualifier:
no guideline followed
Principles of method if other than guideline:
visual description of the colour (in daylight by an observer with normal colour vision) and the physical state (at 20°C and 1013 hPa)
GLP compliance:
no
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid: particulate/powder
Colour:
off-white to slight yellow
Odour:
other: not determined
Substance type:
organic
Conclusions:
- physical state at 20°C and 1013 hPa: solid (powder)
- colour: off-white to slight yellow
- odour: not determined
Executive summary:

The visual description of the colour and the physical state result in the following: 2-hydroxy-1-[4-(4-(2-hydroxy-2-methylpropionyl)phenoxy)phenyl]-2-methylpropan-1-one is an off-white to slight yellow powder at 20°C and 1013 hPa.

Description of key information

- form: solid (powder) at 20°C and 1013 hPa
