The compound binds to rat cytochrome P-450 and the binding can be increased by phenobarbital induction; however, concurrent treatment with piperonyl butoxide failed to influence CFC-113 toxicity due principally to the extremely limited biotransformation of this compound in vivo.
The ratio of retained CFC to that found in expired air suggests that some metabolism does occur. The rate is, however, so low that it could not be concluded with certainty that CFC-113 is metabolized by man.

Arterial and venous concn of 3 C2 fluorocarbons were obtained in unanesthetized beagle dogs during and after 10 min of exposures. Blood concn increased rapidly during the 1st 5 min of exposure and more slowly or not at all thereafter. At termination of exposure, fluorocarbon blood concn decreased rapidly at 1st, followed by a more prolonged decline. An arterial-venous difference, observed during and after exposure, suggested a tissue uptake of fluorocarbon. Although a wide range of inspired concn 0.5% fluorocarbon 113, 2.5% fluorocarbon 114, and 15.0% fluorocarbon 115, is needed to produce cardiac sensitization, arterial or venous fluorocarbon concn associated with these sensitizing levels differ only slightly among the cmpds tested: 12.5, 13.8, and 5.8 ug/mL arterial and 4.9, 7.2 and 3.9 ug/mL venous respectively. Sensitizing blood levels from 25-35 ug/mL arterial and from 18-23 ug/mL venous were reported for C1 fluorocarbons 11 and 12.

吸收、分配和排泄
人类对CFC 113的暴露主要是通过吸入,大部分会通过呼出迅速从体内清除。
Human exposure to CFC 113 is predominantly by inhalation and most of it is rapidly cleared from the body by exhalation.
Animal exposure studies indicate that CFC 113 partitions preferentially into lipid-rich tissues and is poorly metabolized. Loss of CFC 113 from all tissues is rapid during post-exposure periods with virtually 100% clearance within 24 hr after cessation of acute exposure.
Human & animal studies indicate rapid excretion of inhaled FC-114. In a study with radiolabeled FC-114, 30 min retention of the dose inhaled in a single breath was 12% versus 23%, 10%, & 20% for comparable doses of FC-11, FC-12, and FC-113, respectively.

The rate constants for the halogen-atom-transfer reactions between transition-metal complex anion radicals (L(OC) x−1 M •− ) and up to 14 halogenated methanes and ethanes (RX) were measured in a flowing afterglow apparatus

ESR spectroscopy has been used to study the structures and reactions of the radical cations produced from the three- and four-membered sulfur-containing ringcompounds, thiirane and thietane, the radical cations being generated by ..gamma.. irradiation of dilute solutions of the parent compounds in Freon matrices at 77 K. With use of CFCl/sub 3/ as the matrix, the monomer radical cations have been
