Additional information

Based on available data from the reliable publication,the melting point of chemical 4-ethyl-2,3-dioxopiperazine-1-carbonyl chloride was determined  to be in the range of 95 degree C to 96 degree C.

Other supporting studues from authoritative database and safety data sheet indicates that the melting point of chemical 4-ethyl-2,3-dioxopiperazine-1-carbonyl chloride was determined  to be in the range of 96 degree C to 100 degree C.

Also,Prediction was done using the EPI Suite MPVPBP V1.43,the melting point of chemical4-ethyl-2,3-dioxopiperazine-1-carbonyl chloridewas predicted to be 170.26 degree C.

As per the available data from publication has k2 reliability which has the value of melting point as 95 degree C to 96 degree C,  thus considered as key study for the chemical safety assessment.
