87.6 °C

Additional information

In an experiment conducted by SSS(Europe)AB ,the melting point determination of 3-Hydroxyacetophenone (CAS No. 121-71-1) 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 determined to be 87.6 °C - 90.6°C at 977.2hPa

Other supporting studies from authoritative database also suggests that the melting point of chemical 3'-Hydroxyacetophenone was determined to be in he range of 94.83 degree C to 96 degree C. As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of melting point temperature as 87.6 degree C to 90.6 degree C thus considered as key study for the chemical safety assessment
