Principles of method if other than guideline:
Unfortunately we do not have more detailed information about the measurement of the density. But the data provided meet generally accepted
scientific principles and were already evaluated by international experts within the OECD-HPV programme (cf OECD SIDS Dossier Methacrylamide
Mitsui Inc., Japan 2002). This key study was selected as critical study for OECD SIDS of Methacrylamide.

Key result
1.14 g/cm³
25 °C
Density: 1.14 g/cm³ at 25 °C
Executive summary:

In a peer reviewed document of the Japanese government the density of methacrylamide was reported to be 1.14 g/cm³ at 25 °C.

Description of key information

The density of methacrylamide is reported to be 1.14 g/cm3 according Japanese method  JIS K7112-1980(reported in OECD SIDS).

Key value for chemical safety assessment
