Electric Literature of 54232-43-8, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 54232-43-8, name is 6-Bromo-5-methoxypicolinic acid. This compound has unique chemical properties. The synthetic route is as follows.
A mixture of 6-bromo-5-methoxy-pyridine-2-carboxylic acid (0.3 g, 1 mmol), 3-chlorophenylboronic acid (CAN 63503-60-6, 0.23 g, 1 mmol), tris(dibenzylidene-acetone)-dipalladium(0) (CAN 52409-22-0, 0.12 g), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (CAN 161265-03-8, 0.15 g) and potassium carbonate (0.21 g, 2 mmol) in 1,4-dioxane (10 mL) was stirred for 12 h at 110 C. under a nitrogen atmosphere. The reaction mixture was filtered, concentrated under reduced pressure and purified by column chromatography (silica gel, 10 g, eluting with 10% methanol in methylene chloride) to give the title compound (0.1 g, 29%); MS (EI): m/e=264.0 [M+H]+.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 54232-43-8, 6-Bromo-5-methoxypicolinic acid.
