- Specific details on test material used for the study:
- Iodobis(triphenylphosphino)copper (Bruggolen® H3301), batch no. 07103001
- Key result
- Melting / freezing pt.:
- >= 186.5 - <= 197.4 °C
- Conclusions:
- All validity criteria were met. The test item Iodobis(triphenylphosphino)copper (H3301) showed no defined melting point, but a wide melting range of 186.5 to 197.4 °C (459.7 to 470.6 K).
As the melting point is very high, no impact on assessment of the behavior of Iodobis(triphenylphosphino)copper (H3301) in the environment or when handling in industrial processes is expected due to the remaining uncertainty concerning the exact melting point.
No observations were made, which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid. - Executive summary:
The determination was performed in duplicate. In both determinations, a melting range was detected.
The melting range was determined as 186.5 to 197.4°C (459.7 to 470.6 K) these values being the mean of two independent determinations.
The melting point of the reference item lay in the accepted range.
