Febuxostat methanol solvate

Abstract

In the title compound {systematic name: [2-(3-cyano-4-isobutyloxyphenyl)-4-methyl-1,3-thiazole-5-carboxylic acid (febuxostat) methanol monosolvate}, C16H16N2O3S·CH4O, the benzene and thiazole rings in the febuxostat molecule are twisted at 5.3 (1)°. In the crystal structure, intermolecular O—H...O and O—H...N hydrogen bonds link the febuxostat and methanol molecules into helical chains along the 21 screw axis.
