Metabolites of bis(2-chloroisopropyl)ether in the rat included 1-chloro-2-propanol, propylene oxide, 2-(1-methyl-2-chloroethoxy)-propionic acid, and carbon dioxide.
Evaluation: No epidemiological data relevant to the carcinogenicity of bis(2-chloro-1-methylethyl)ether were available. There is limited evidence in experimental animals for the carcinogenicity of bis(2-chloro-1-methylethyl)ether. Overall evaluation: Bis(2-chloro-1-methylethyl)ether is not classifiable as to its carcinogenicity to humans (Group 3).

After single oral doses, bis(2-chloroisopropyl) ether (BCIE) appeared to be readily absorbed by both /female rats and monkeys/. In the monkey, the blood radioactivity level reached a high peak within two hr and then declined in a biphasic manner, with a half-life of about five hr and greater than two days for the first & second phases, respectively. In the rat, the blood radioactivity level reached a maximum between 2 and 4 hr after dosing and then slowly declined with a half-life of two days. There was a substantial difference in the tissue distribution and excretion pattern seven days after a single parenteral dose of 30 mg/kg of (14)C-BCIE. The monkey retained substantially higher amounts of radioactivity in the liver (equivalent to 28.8 ug/g BCIE) than did the rat (3.2 ug/g). Higher quantities were also found in the muscle; brain of the monkey. ... With respect to the percentage of admin dose recovered in the tissues and excreta, higher amounts of radioactivity were found in the fat (1.98%), urine (63.36%), feces (5.87%), and expired air (15.96%) of the rat. The corresponding figures in the monkey were 0.78%, 28.61%, 1.19%, and 0%.
