yes

Decomp. temp.:

> 250 - < 330 °C

Remarks on result:

not determinable because of methodological limitations

Remarks:

Decomposition of the test substance were observed approximately 250 -300 °C

Conclusions:

According to OECD 102 test method, CR SB37 has no melting temperature.

Executive summary:

This test using the procedures outlined in the ECIC Study Plan for 170215-01 and OECD 102. Decomposition of the test substance were observed approximately 250 -300 °C and melting of the test substance was not observed below the temperature at which decomposition started. Therefore, the test substance has no melting temperature.

Description of key information

CR SB37 has no melting temperature (OECD TG102).

Additional information

Decomposition of the test substance were observed approximately 250 -300 °C and melting of the test substance was not observed below the temperature at which decomposition started. Therefore, the test substance has no melting temperature.
