Conclusions:

The melting point determination of test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The test was conducted in replicates. No change was observed in state of test chemical upto 300°C, and thus, the melting temperature was inferred to be > 300°C at 977.0 hPa

Executive summary:

The melting point determination of test chemical was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. The test was conducted in replicates. No change was observed in state of test chemical upto 300°C, and thus, melting temperature was inferred to be > 300°C at 977.0 hPa
