The estimated vapour pressure of the test substance Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate at 25deg C was 6.84E-12 Pa (5.13E-14 mm Hg).
Executive summary:

Modified Grain method (Mean of Antoine and Modified Grain methods) was used to estimate the vapour pressure of the test substance Reaction mass of 3H-​Indolium, 2-​[[2-​(4-​methoxyphenyl)​-​2-​methylhydrazinyliden​e]​methyl]​-​1,​3,​3-​trimethyl-​ & acetate using MPBPVP v1.43 of EPI SUITE.

The estimated vapour pressure of the test substance 2-[[(4-methoxyphenyl)methylhydrazono]methyl]-1,3,3-trimethyl-3H-indolium acetate at 25deg C was 6.84E-12 Pa (5.13E-14 mm Hg).
