Absorption, Distribution and Excretion
The absorption of diphenyl ether after oral uptake is up to 90% in rats and rabbits and is independent of the administered dose. The data on dermal absorption are somewhat conflicting. After semi-occlusive application of 10-1,000 mg/kg to the clipped skin of rats, almost 20% of the dose was absorbed as measured by the amount excreted in urine. However, in a diffusion experiment only 0.3% (rat skin) or 0.2% (human skin) of diphenyl ether penetrated the skin in vitro. The higher absorption in the in vivo experiment may have been caused by the vehicle (diethyl phthalate) and some oral uptake after removal of the occlusion plaster.
After intraperitoneal injection in rats, diphenyl ether was distributed into all organs and tissues within 1 hour with maximum concentrations in liver, lung, kidney and spleen.
... Phenyl ether, when injected into the rabbit, was excreted in the urine as p-hydroxyphenyl phenyl ether and none was excreted as the unchanged ether. /Route not specified/

Metabolism / Metabolites
... In the rabbit no cleavage of the ether linkage /of phenyl ether/ occurs. The major metabolite was the p-hydroxylated ether, which is excreted both unconjugated (15%) and conjugated with glucuronic acid (63%) and sulfuric acid (12%). Another metabolite was also isolated from the rabbit urine and fairly well identified as di(p-hydroxyphenyl) ether.
Subcellular fractions of trout liver homogenate metab diphenyl ether mainly to 4 hydroxy derivates with traces of other compounds including 3 hydroxy derivates and possibly 4,4'-dihydroxy derivates.
The bacterium Sphingomonas sp strain SS3, which utilizes diphenyl ether as source of carbon and energy, was enriched from soil samples of an industrial waste deposit. During diphenyl ether degradation in batch culture experiments, phenol and catechol were produced as intermediates which were then channeled into the 3-oxoadipate pathway. The initial step in the degradation follows the recently discovered mechanism of 1,2-dioxygenation, which yields unstable phenolic hemiacetals from diphenyl ether structures.
Screening of selected fungi proved Cunninghamella echinulata most suitable for research on hydroxylation of biphenyl oxide. The process depended on cultivation conditions and yielded up to 76% 4-hydroxybiphenyl oxide and about 6% 4,4'-dihydroxybiphenyl oxide.

Diphenyl oxide appears as colorless liquid with a mild pleasant odor. May float or sink in water. Freezing point is 81 °F. (USCG, 1999)
Diphenyl ether is an aromatic ether in which the oxygen is attached to two phenyl substituents. It has been found in muscat grapes and vanilla. It has a role as a plant metabolite.
Diphenyl ether has been reported in Vitis vinifera and Mangifera indica with data available.
