Urethane has been primarily used in research settings as an anesthetic agent in animal studies, although its use is now heavily restricted due to its classification as a carcinogen. In addition to its historical applications in pharmacology, urethane is also utilized in the synthesis of various chemical compounds, including pharmaceuticals and agrochemicals. Its properties make it a subject of interest in toxicology studies, where researchers investigate its effects on biological systems. Furthermore, urethane is sometimes used in the production of certain polymers and coatings, although such applications are limited due to safety concerns.
