(E)-1-(Pyridin-4-yl)propan-1-one O-tosyl oxime

The title compound, C15H16N2O3S, was obtained by the reaction of (E)-1-(pyridin-4-yl)propan-1-one oxime and para-toluene­sulfonic acid. The pyridine ring makes a dihedral angle of 54.70 (10)° with the benzene ring. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming a chain along the c-axis direction.
