14 C‐uniformly ring labeled 3,3′,5,5′‐tetra‐ tert ‐butyldiphenoquinone was synthesized from 2,6‐di‐ tert ‐butylphenol. Chemical purity was established by mixed melting point, thin‐layer and gas‐liquid chromatography. Radiochemical purity was determined using auto‐radiography in conjunction with thin‐layer chromatography and liquid scintillation techniques. Structure was confirmed by elemental analysis, ultraviolet‐visible and infrared spectroscopy and nuclear magnetic resonance.
