Structure of 5-methyl-7-methoxy-isoflavone

Concomitant polymorphs of methoxyflavone (5-methyl-7-methoxyflavone)

“…18,19 Currently, the systematic explorations on polymorphism of methoxy-avone were not reported much, only one crystal structure of methoxyavone was reported earlier. 20 In the screening and evaluation process the proper polymorphs should be used to avoid the unwanted other polymorphs to change the bioavailability, solubility and stability of the pharmaceutical reagents. [21][22][23] In this work, two conformation polymorphs of methoxyavone were isolated and identied (the original structure was designated form A), and an amorphous phase was also acquired.…”
