Abstract: The title compound, C₁₅H₂₂NO₄S, is a nitroxyl radical, which is stable mainly because the N atom is surrounded by tertiary C atoms, preventing formation of the nitrone. More significantly, intermolecular C-HO hydrogen bonding contributes to the stability of the structure with weak intramolecular C-H(arene) interactions. The N-O distance is 1.2816 (18) Å.
