CAS:4'-tert-Butyl-2',6'-dimethyl-3',5'-dinitroacetophenone is a ketone that is used in the synthesis of new chemical substances. It has been shown to have toxicological properties and can be used for the treatment of bacterial infections. 4'-tert-Butyl-2',6'-dimethyl-3',5'-dinitroacetophenone has been shown to produce a high degree of solubility in water, which is an advantageous property for wastewater treatment because it allows for easy removal of this compound from contaminated water.Fórmula:C14H18N2O5Pureza:Min. 95%Cor e Forma:PowderPeso molecular:294.3 g/molEosin Y disodium salt
CAS:Eosin Y, a red xanthene dye, has been noted to reduce the affinity of Mg2+-ATPase for ATP and increase the enzyme affinity for Mg2+ at concentrations of 10-50 μM. At higher concentrations near 100 μM the affinity for Mg2+-ATPase for the ion-activator has been shown to be reduced. This compound has also been reported to be a photosensitizer that works as a molecular photoelectrode via catalyzation of the visible-light-driven electron-transfer reaction. Eosin Y has been used to stain structures such as muscle, cytoplasm, and collagen. This agent also enhances fluorescent quenching abilities by forming a complex with polyvinulpyrrolidone.
