Because of enantiotropy, the commercial forms of three of the compounds did not consist of the modification with the highest melting point: These were 4-hydroxy-3,5-dimethoxybenzoic acid (4 modifications), 3-pyridylacetic acid (4 modifications) and 2,4,5-triaminopyrimidine (4 modifications). In contrast, 2-amino-2-cyanoacetamide (3 modifications) and [([(4-methylphenyl)sulphonyl]oxy)imino]propanedinitrile (7 modifications) were present in the highest melting form in the commercial products. A further 32 compounds (most of which had only two modifications) were examined and are reported without detailed results; six of them were enantiotropic.
