- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- powder
- Colour:
- Blue
- Conclusions:
- The test item is a solid at 1013 hPa in a range of 25 °C and 160 °C.
- Executive summary:
Method:
Differential Scanning Calorimetry (DSC) according to the OECD Test Guidelines 102 and 103.
Results:
Between 25 and 160°C there is a release of imbibition/crystallisation water. Between 244-423°C is registered an exothermic effect (onset = 282.3°C, enthalpy = 1673 J/g).
Conclusion:
The test item is a solid at 1013 hPa in a range of 25°C and 160°C.
- Endpoint:
- appearance / physical state / colour
- Type of information:
- other: Qualitative assessment
- Adequacy of study:
- weight of evidence
- Study period:
- 2018
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Justification for type of information:
- All evaluations are based on information about specification (technical standard), experience in dealing with the substance and visual evaluation of several different batches.
- Principles of method if other than guideline:
- Qualitative assessment
- GLP compliance:
- no
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- powder
- Colour:
- Blue
- Conclusions:
- The substance is a blue powder at 20 °C and 101325 Pa.
- Executive summary:
The substance has been evaluated for its appearance. It is a blue powder at 20 °C and 101325 Pa.
