1-propenylmagnesium bromide - Introduction
1-propyl magnesium bromide is an organic compound with the chemical formula C3H7MgBr. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 1-propylmagnesium bromide is a colorless to pale yellow liquid.
-Solubility: Soluble in ether, ethanol and dimethylformamide, insoluble in water.
-Melting point: approximately at -50°C.
-Boiling point: Under normal pressure, its boiling point is about 110°C.
Use:
- 1-propyl magnesium bromide is commonly used as a reagent in organic synthesis.
-It can be used as an alkylation reagent in organic synthesis, and is often used to introduce propyl groups.
