While Ethylmagnesium Bromide (CAS 925-90-6) is widely recognized for its broad utility in organic synthesis and pharmaceutical manufacturing, its specialized application in lipid chemistry, particularly in the regiospecific analysis of triacylglycerols (TAG), warrants specific attention. For researchers in food science, nutrition, and biochemistry, understanding how this Grignard reagent aids in detailed fatty acid profiling is crucial.

In the field of lipid chemistry, accurately determining the composition of fatty acids at specific positions (sn-1, sn-2, and sn-3) within TAG molecules is vital for understanding metabolic pathways, nutritional profiles, and the quality of fats and oils. This process, known as regiospecific analysis, often involves the partial deacylation of TAGs. Here, Grignard reagents such as Ethylmagnesium Bromide play a pivotal role. When used to treat TAGs, it helps to selectively cleave ester bonds, yielding monoacylglycerols (MAG) and diacylglycerols (DAG) that can then be analyzed to determine the fatty acids present at the sn-1 and sn-2 positions.

Ethereal solutions of Ethylmagnesium Bromide, typically at concentrations of 0.5-3 M, are commonly employed for this purpose. The precision offered by this reagent is essential, as even minor contamination from fatty acids migrating between positions can skew analytical results. Researchers looking to buy Ethylmagnesium Bromide for such specialized analyses will prioritize suppliers who can guarantee a high assay (e.g., 99% or higher) and consistent performance. Partnering with a manufacturer that provides detailed product specifications and adheres to quality standards ensures the reliability of these critical experiments.

For procurement managers sourcing this chemical for lipid analysis, understanding the source and quality is as important as in pharmaceutical synthesis. While the price of Ethylmagnesium Bromide can vary, focusing on suppliers who provide documentation and support, such as those offering USP, BP, EP, FCC compliance and potentially GMP certifications, is advisable even for research applications. Manufacturers in China are a significant source for high-quality reagents like Ethylmagnesium Bromide, often offering competitive pricing and various packaging options suitable for laboratory use. When you need to purchase this reagent for your lipid studies, inquire about availability and obtain a quote from a trusted chemical supplier.

By leveraging the power of Ethylmagnesium Bromide in lipid analysis, scientists can achieve greater accuracy in characterizing complex lipid structures, contributing to advancements in various scientific and industrial fields.
