CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID | [Uses]
Diethyl Bromomalonate is a chemical constituent of the asymmetric cyclopropanation of chalcones. Also used in the preparation of nanaplatforms for NIR imaging-guided photodynamic therapy of cancer cel
ls. | [Uses]
Diethyl bromomalonate is used in perfumes. It is also used to synthesize other compounds such as barbiturates, artificial flavorings, vitamin B1, and vitamin B6. | [Synthesis]
The Preparative Method of Diethyl Bromomalonate: by light-induced bromination of Diethyl Malonate with bromine in carbon tetrachloride; by treatment of diethyl malonate with bromotrichloromethane and 1,8-Diazabicyclo[5.4.0]undec-7-ene in benzene at 0 °C.
