In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. 144-48-9, formula is C2H4INO, Name is 2-Iodoacetamide.Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. Formula: C2H4INO.
Ratanaphain, Chatkrita;Viboonratanasri, Duangkamon;Prompinit, Panida;Krajangpan, Sita;Khan, Eakalak;Punyapalakul, Patiparn research published 《 Reactivity characterization of SiO2-coated nano zero-valent iron for iodoacetamide degradation: The effects of SiO2 thickness, and the roles of dehalogenation, hydrolysis and adsorption》, the research content is summarized as follows. The effect of SiO2-layer thickness in SiO2-coated nano zero-valent iron (nZVI) particles on the reactivity characteristics of iodoacetamide (IAcAm) degradation was evaluated. SiO2-layer thicknesses ranging from 3.6 to 27.3 nm were obtained through varying tetra-Et orthosilicate dosages of 0.001-1 M. The crystallinity, surface chem. composition, and physicochem. properties were evaluated for their effects on synergetic degradation mechanisms, dehalogenation, hydrolysis, and adsorption. At a thickness of 3.6 nm, the SiO2 layer offered the highest observed pseudo-first-order rate (kobs) and higher rates of IAcAm degradation were maintained under pH fluctuations (pH 5-7) and aerobic conditions compared to pristine nZVI. At this SiO2-layer thickness (3.6 nm), the rate of iron oxide-layer formation was reduced and the migration of reactive iron species (Fe0 and Fe2+) for the dehalogenation and hydrolysis reactions was enabled. In a single-solute solution, IAcAm elimination was greater than bromoacetamide and chloroacetamide elimination due to the weak ionic I-C bond. In mixed solute conditions, the hydrophobicity of chloroacetamide played a more significant role in competitive degradation through greater adsorption. The proportion of dehalogenation relative to hydrolysis during IAcAm degradation by pristine nZVI and SiO2-coated nZVI was approx. 0.6:0.4. Iodoacetic acid and acetic acid were detected as intermediates in the degradation pathway of IAcAm by pristine nZVI. In contrast, the SiO2 layer on nZVI can accelerate the transformation of IAcAm to acetamide and iodoacetic acid. The electrolyte background of tap water exhibited a slight inhibitory effect on the degradation of IAcAm for both nZVI and SiO2-coated nZVI.
Formula: C2H4INO, 2-Iodoacetamide is a synthetic retinoid that binds to the DNA of cells, altering transcription. It also has been found to be effective in treating bowel disease and has been shown to have dna binding activity. The compound was synthesized by attaching iodine molecules to acetamide. 2-Iodoacetamide targets the protein thiols on the surface of cells, which are responsible for oxidation and damage due to reactive oxygen species (ROS). This compound is metabolized by alcohol dehydrogenase and can be used as a biological sample or natural compound is a compound used as an electrophile for covalent modification of nucleophilic residues on proteins (cysteine, methionine, histidine). When modifying the active-site residues of cysteine proteases, α-Iodoacetamide acts as an irreversible inhibitor of these enzymes.
2-Iodoacetamide used in peptide mapping because it covalently binds with thiols in cysteine residues, thereby preventing disulfide bond formation. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. Also reacts with histidine residues though much more slowly, and this activity is responsible for inhibition of ribonuclease.
An alkylating sulfhydryl reagent. Its actions are similar to those of iodoacetate., 144-48-9.
