CARBAMIC ACID BENZYL ESTER - Reference Information
| NIST chemical information | information provided by: webbook.nist.gov (external link) |
| Use | organic synthesis intermediates. used as a reagent for organic synthesis. |
| production method | results from the interaction of benzyl chloroformate with ammonia. Benzyl chloroformate was slowly added to 5 volumes of cold aqueous ammonia (relative density 0.90) under vigorous stirring, the reaction mixture was left at room temperature for 30min, the precipitate was filtered off, washed with water and dried to obtain a finished product. |
