Abstract: In the title compound, C21H26O2SSe, the S atom adopts a pyramidal geometry (bond-angle sum = 304°) and the n-butyl chain shows an extended conformation. An intra­molecular C-H...O hydrogen bond closes an S(8) ring. In the crystal, inversion dimers are formed with molecules linked by pairs of O-H...O=S hydrogen bonds, generating R22(14) loops. Weak C-H...O inter­actions also occur.
