Additional information

The melting point determination of test substance was done as per the test guideline OECD 102. The method followed was according toCapillary/metal block. The melting point was determined to be in range of 80°C-85°C at 970.4 hPa.

From other experimental reports,the melting point of test chemical by the capillary method is found to be 86°C at an atmospheric pressure of 970 hPa.There was no decomposition & sublimation observed.

Also from other reliable sources, melting point of test chemical is observed to be in the range of 86 - 89 degree C.
