title: Febuxostat methanol solvate.
abstract: In the title compound {systematic name: [2-(3-cyano-4-isobutyl-oxyphen-yl)-4-methyl-1,3-thia-zole-5-carb-oxy-lic acid (febuxostat) methanol monosolvate}, C(16)H(16)N(2)O(3)S·CH(4)O, the benzene and thia-zole rings in the febuxostat mol-ecule are twisted at 5.3 (1)°. In the crystal structure, inter-molecular O-H⋯O and O-H⋯N hydrogen bonds link the febuxostat and methanol mol-ecules into helical chains along the 2(1) screw axis.
