The present study aimed to obtain new crystalline forms of 5-fluorouracil (5-FU) chemotherapy drug after 5-FU solvation in different solvents, considering the crystallization by slow evaporation. The expectation was to obtain 5-FU polymorphs. 5-FU was tested in aqueous solutions of 14 solvents. After slow evaporation of solutions (11) or suspensions (3), the obtained crystalline forms were examined by checking their X-ray diffraction patterns. Only for acetonitrile solution resulted a polymorph of 5-FU.
Key words: 5-fluorouracil; solubility; X-ray diffraction; polymorphs.
