We provide high-quality Ethyl (3-Oxo-3-Phenylpropyl) Carbamate, also known as ethyl carbamate or urethane, with the CAS number 358-23-6. It is a colorless to white crystalline solid with a molecular weight of 214.25 g/mol, a melting point of 92-93 °C, and a boiling point of 305 °C. It is soluble in water and slightly soluble in alcohol.


Ethyl (3-Oxo-3-Phenylpropyl) Carbamate is used as an intermediate in the production of organic and pharmaceutical chemicals. It is also used as an intermediate in the manufacture of flavoring agents, perfumes and dyes. It is also a potential chemical intermediate for the production of pharmaceuticals.


Ethyl (3-Oxo-3-Phenylpropyl) Carbamate is highly toxic and needs to be handled with extreme care. It is flammable and should be stored in a cool, dry place, away from light and sources of ignition. It should also not be exposed to temperatures above its melting point. When handling this material, protective clothing and safety equipment should be used.
