α-Iodoacetamide (CAS 144-48-9)

α-Iodoacetamide is a chemical compound that is used as an alkylating agent in biochemistry and proteomics studies. α-Iodoacetamide is primarily utilized for the modification of cysteine residues in proteins. Researchers use α-Iodoacetamide to selectively react with the thiol group (-SH) of cysteine residues, forming a covalent bond. This process, known as alkylation, effectively blocks the cysteine residues and prevents unwanted disulfide bond formation or oxidative reactions during protein analysis. α-Iodoacetamide is particularly useful in proteomics research, where it is employed in techniques such as gel electrophoresis, liquid chromatography, and mass spectrometry. By modifying cysteine residues with α-iodoacetamide, researchers can study various protein properties, including protein structure, function, and interactions. This compound facilitates the identification and quantification of cysteine-containing peptides, allowing for comprehensive analysis of protein samples. Furthermore, α-iodoacetamide can be employed in studies involving protein folding, protein-protein interactions, and post-translational modifications.
