Additional information

Based on available data from various authoritative database, the melting point of chemical tetraethyl [1,4-phenylenebis(methylene)]bis(phosphonate) ester was determined to be in the range of 72 degree C to 73 degree C.

Other supporting study from reliable safety data sheet also indicates that the melting point of chemical tetraethyl [1,4-phenylenebis(methylene)]bis(phosphonate) was determined to be 73 degree C

Also further supported by the prediction done using the EPI Suite MPVPBP V1.43,to predict the melting point of chemical tetraethyl [1,4-phenylenebis(methylene)]bis(phosphonate) ester.

The melting point of chemical tetraethyl [1,4-phenylenebis(methylene)]bis(phosphonate) ester was estimated to be 75˚C,and the selected key study lies in the range as mentioned above.
