Additional information

REAXYS reports the dissociation constant of 2-ethyl-4-methylimidazole as result from experimental study to be 8.5 at 25°C. In addition a QSAR estimation was done using SPARC v4.5 with the result of 7.89 at 25°C. The value which originates from REAXYS which is a peer reviewed data base was chosen as key value for the dissocition constant for 2-ethyl-4-methylimidazole.
