The metabolism and disposition ofortho‐benzyl‐para‐chlorophenol (BCP) has been investigated in the male rat following an oral dose of 69 mg/kg or 206 mg/kg. BCP was rapidly eliminated at both dose levels with 45–49% of the dose appearing in the urine and 44–49% in the feces during the 5‐d period after dosing. After 5 d only 0.28–0.3% of the dose remained in the body, with almost half this value accounted for in the liver and kidney. The dynamics for the overall elimination of radioactivity from the body was biphasic at both dose levels. The initial rapid a phase had a well defined half‐life of 8–9 h, and the slower β phase had an estimated half‐life of approximately 52–140 h.
