Synthesis of 1 3-propane sultone
Web1,3-Propane sultone is used as a chemical intermediate to introduce sulfopropyl groups into molecules and to confer water solubility and anionic character. Solubility Soluble in water (100 mg/ml), chloroform, esters, methanol, and aromatic hydrocartions. Notes Special handling precautions required. View MSDS prior to purchase. Webluminescent acridine ester precursors with the toxic carcinogen 1,3-propane sultone. In the current study, we report that sodium 3-bromopropane sulfonate in ionic liquids (ILs) is a benign alternative to 1,3-propane sultone for introducing the N-sulfopropyl group in chemiluminescent acridinium ester labels. The sultone reagent can be
