:N-Ethylmaleimide
Description:
N-Ethylmaleimide is an organic compound characterized by its maleimide structure, which features a five-membered ring containing a carbonyl group and a nitrogen atom. It is a colorless to pale yellow liquid at room temperature, exhibiting a distinctive odor. This compound is known for its reactivity, particularly in forming covalent bonds with nucleophiles, making it a valuable reagent in organic synthesis and biochemistry. N-Ethylmaleimide is often used in the modification of proteins and peptides, as it can selectively react with thiol groups, facilitating the study of protein structure and function. Additionally, it is utilized in the production of polymers and as a cross-linking agent in various chemical processes. The compound is soluble in organic solvents such as acetone and ethanol but has limited solubility in water. Safety precautions should be taken when handling N-Ethylmaleimide, as it can be irritating to the skin and eyes, and proper storage conditions are necessary to maintain its stability.

CAS:N-Ethyl maleimide is a cytosolic calcium chelator that binds to the calcium ions in the cells. It has been shown to inhibit the enzymes of fatty acid synthesis and phospholipase A2, which are involved in lipid metabolism. N-Ethyl maleimide is an irreversible enzyme inhibitor and can be used as a chemical tool for cell sample preparation. The reaction with N-ethyl maleimide leads to a decrease in water permeability of the cell membrane. This chemical also has a high affinity for sulfhydryl groups and can therefore be used as an anti-oxidant or free radical scavenger.Formula:C6H7NO2Purity:Min. 95%Color and Shape:PowderMolecular weight:125.13 g/molN-Ethyl Maleimide (1M Solution in Acetonitrile)
