Only for two of them is the highest melting form the stable form at room temperature. Enantiotropy between the commercial form and the higher melting modifications was observed for aminoacetonitrile hydrochloride (3 modifications), 3,4-dinitrobenzoic acid (4 modifications), 5,6-diphenyl-3-(2-pyridyl)-1,2,4-triazine (3 modifications) and (2-furyl)oxoacetamide (3 modifications). 2-Biphenyl-5-phenyl-1,3,4-oxadiazole (5 modifications) and (+-)-4-chloromandelic acid (3 modifications) can be assumed to be monotropic, but exact information about the modifications was impossible to obtain.
