乙基溴化镁 (CAS No.925-90-6)
- 物化性质
- 通常以乙醚或四氢呋喃溶液形式供应，为无色至黄色透明液体，具有强烈刺激性气味。对空气和水分极其敏感，遇水剧烈反应并放出可燃气体，遇氧气易分解。密度随溶剂和浓度不同而异，3.0M四氢呋喃溶液密度约0.95～1.05 g/cm³，溶剂沸点约65℃，闪点极低（约-14℃）。溶于乙醚、四氢呋喃等有机溶剂，需在惰性气体保护下低温避光储存。
- 纯度
- ≥99%
- 外观
- 无色至黄色透明液体

Product Name:Ethylmagnesium bromide
English Name:Ethylmagnesium bromide
CAS No.:925-90-6
Aliases:Ethyl magnesium bromide, Bromoethyl magnesium, Magnesium, bromoethyl-
Molecular Formula:C2H5MgBr
Physical Properties:Typically supplied as a solution in diethyl ether or tetrahydrofuran (THF), appearing as a colorless to yellow transparent liquid with a strong pungent odor. It is extremely sensitive to air and moisture, reacting violently with water to release flammable gases and decomposing in oxygen. Its density varies with solvent and concentration; a 3.0 M THF solution has a density of approximately 0.95–1.05 g/cm³, a solvent boiling point of about 65°C, and a very low flash point (approximately -14°C). It is soluble in ether and THF, and must be stored under inert gas at low temperature away from light.
Uses:Widely used for carbon-carbon bond formation in organic synthesis, such as the preparation of alcohols, carboxylic acids, and alkylated derivatives. It is extensively applied in the synthesis of pharmaceutical intermediates, agrochemicals, and fine chemicals due to its mild reaction conditions and high selectivity. As a Grignard reagent, it is also used in nucleophilic addition and cross-coupling reactions. Due to its high reactivity, it must be handled under strict exclusion of air and moisture.
Technical Specifications:
Concentration: 3.0 M in tetrahydrofuran
Purity: ≥99%
Appearance: colorless to yellow clear liquid
Water content: ≤0.1% (Karl Fischer method)
Packaging: 200 kg/drum, sealed under nitrogen
