81742-10-1, 3,6-Dichlorotrimellitic Anhydride is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Dibenzofuran-1,3-diol (prepared according to Carvalho, C. F. et al. (Supra)) (200 mg, 1 mmol), 2-fluoronaphthalene-1,3-diol 34 (178 mg, 1 mmol, AB part number 361828) and anhydrous 2,5-dichlorotrimellitic acid (260 mg, 1 mmol, AB part number 361892) were mixed in methanesulfonic acid (10 mL). Then, the mixture was stirred at 130 to 135 C. for 2 hours. The reaction mixture was cooled and mixed with ice water (100 mL). The precipitated dye was extracted with ethyl acetate (100 mL). The organic layer was washed with water (50 mL ¡Á 2) and washed with brine (50 mL ¡Á 1). After drying over sodium sulfate, the mixture was filtered, the solvent was removed, and the crude pigment was obtained as an isomeric mixture. These isomers were separated by thin layer chromatographic separation and 80 mg (13%) of a dye was obtained., 81742-10-1
As the paragraph descriping shows that 81742-10-1 is playing an increasingly important role.
