Abstract: The asymmetric unit of the title compound, C13H11N3O5S, contains two independent mol­ecules, which are linked by a pair of inter­molecular N-H...S hydrogen bonds, forming an R22(8) ring motif. The central thio­urea core forms dihedral angles of 3.02 (12) and 14.00 (10)° with the essentially planar furoyl groups [maximum deviations = 0.030 (2) and 0.057 (2) Å] in the two mol­ecules and dihedral angles of 2.43 (13) and 8.03 (12)° with the benzene rings. The dihedral angles between the furoyl and benzene rings in the two mol­ecules are 3.97 (10) and 5.98 (9)°. The trans-cis geometry of the thio­urea group is stabilized by three intra­molecular N-H...O hydrogen bonds involving carbonyl and meth­oxy O atoms with the H atom of the cis-thio­amide group and between furan O atom and the other thio­amide H atom. There is also a weak intra­molecular C-H...S inter­action in each mol­ecule.
