53.1 °C

Additional information

The melting point determination of 1,4-Dichloro-2-nitrobenzene (CAS No. 89-61-2) was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and Mean Melting temperature range was determine to be 53.1-55.3°C at 972.1hPa.

The melting point of chemical 2,5-Dichloronitrobenzene is observed to be 56 deg C.

Thus the mean Melting temperature range was determine to be 53.1-55.3°C.
