Reference
Endpoint:
appearance / physical state / colour
Type of information:
other: observation
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: acceptable company statement (specification data on manufactured product requires strict adherence to conform within range and so is reliable)
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)
- Determination of the odour at room temperature and comparison to other substances of characteristic odours
GLP compliance:
no
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
powder
Colour:
white
Odour:
faint
Substance type:
organic
Conclusions:
- physical state at 20°C and 1013 hPa: solid (form: powder)
- colour: white
- odour: faint
Executive summary:

The visual description of the colour, the physical state (at 20°C and 1013 hPa) and the determination of the odour resulted in the following: the test substance 2-hydroxy-3-pyridinium-1-ylpropane-1-sulfonate is a white powder with faint odour (at 20°C and 1013 hPa).

Description of key information

The test substance is a white powder with faint odour (at 20°C and 1013 hPa).
