Ethylmagnesium Bromide, typ. 15 % solution in MTBE (typ. 0.9 M)
C2H5BrMg
Ethylmagnesium Bromide (CAS 925-90-6) is an organomagnesium compound (Grignard reagent) with molecular formula C2H5BrMg. It is supplied as a typical 15% solution in MTBE.
In organic synthesis it is used in Grignard-type reactions as a reactive carbon nucleophile.
Ethylmagnesium Bromide reacts readily with moisture and oxygen and should be handled under dry, inert conditions. Consult the SDS and site-specific procedures for compatible materials, fire response, and storage.
Applications
Grignard-reactions: reagent for the introduction of the ethyl group.
Specifications
- Total Base: 13,0 – 16,0 %
- Active Base: 12,0 - 16,0 %
Method of Analysis
Determination of assay as total base by acidimetric titration after hydrolysis. Determination of active base by Watson-Eastham titration. Detailed description available on request.Handling Instructions
The material should only be handled under inert gas atmosphere. Vapors may form explosive mixtures with air. Vapors are heavier than air and may spread along floors. Flash back possible over considerable distance. Use only explosion-proof equipment. Protect from frost, heat and sunlight. Never add water, acids or oxidizing materials. In case of fire use dry extinguishers based on sodium chloride or limestone powder, never use water or CO2. Pay attention to the Safety Data Sheet - Section 7.
Storage Instructions
When stored according to SDS the material is fairly stable. We still recommend to retest the material 6 month after date of analysis if included on CoA. If not included, use the date of manufacturing for the calculation. The material should be stored below 10 °C. Precipitates cannot be redissolved by warming and appropriate.
