oxidative desulfurization

Ethylenedisulfonic acid dihydrate (1,2-Ethylenedisulfonic acid dihydrate) acts as a structure-forming agent and organic modifier. Ethylenedisulfonic acid dihydrate forms hydrogen-bonded polymer structures via in situ two-component reactions with pyridine-containing compounds. Ethylenedisulfonic acid dihydrate can coat molybdenum oxide supported on carbon nanotubes for oxidative desulfurization. Ethylenedisulfonic acid dihydrate serves as a biochemical reagent for relevant research in various fields such as organic synthesis .

C-TPA is a fluorescent probe used for hypochlorite detection and bioimaging of lipid droplet polarity in cancer cells. For hypochlorite detection, when its derivative C-TPA-S is exposed to hypochlorite, an oxidative desulfurization reaction converts the thiocarbonyl group of C-TPA-S to the carbonyl group of C-TPA, thus restoring bright fluorescence from the almost non-fluorescent C-TPA-S. For bioimaging of lipid droplet polarity, the intramolecular charge transfer process between its Triphenylamine (HY-W011998) donor group and Coumarin (HY-N0709) acceptor group endows C-TPA with solvatochromism-it exhibits stronger fluorescence in less polar environments (such as lipid droplets in cancer cells) and weaker fluorescence in more polar environments (such as lipid droplets in normal cells), enabling the differentiation of cancer cells and cancer tissues from normal cells and normal tissues. The excitation wavelength of C-TPA is 405 nm, and the emission wavelengths used for cell and tissue imaging cover 425-475 nm and 500-550 nm; in solvents, its emission peak shifts from 494 nm in non-polar toluene to 528 nm in polar water .
