“…In the Cambridge Structural Database (CSD, Version 5.43, 2023) 4 there are only a few reports of the crystal structures of organic co-crystals and salts of niflumic acid with bioactive ingredients such as: nicotinamide, 5 sulfamethazine, 6,7 l -proline, 8 caffeine, 9 maleic acid, 10 tyramine, 11 and morniflumate. 12 Moreover, complexes of niflumic acid with caprolactam, pyridin-2(1 H )-one 11 and 4,4′-bipyridine 13 are reported. There are also salts of niflumic acid with non-bioactive components such as: ( R )-1-phenylethylamine, 14 ethanolamine, 15 benzylamine, benzenesulfonic acid, and piperazine.…”
