Related Products of 3430-18-0, 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 3430-18-0, name is 2,5-Dibromo-3-methylpyridine. This compound has unique chemical properties. The synthetic route is as follows.
Method 3; Preparation of 6-bromo-5-methvmicotmaldehvde; 2,5-Dibromo-3-picoline (5.1 g, 20.30 mmol) in tetrahydrofuran (25 ml) was added dropwise to a 2M solution of isopropylmagnesium chloride (10.7 ml, 21.3 mmol) in tetrahydrofuran at 0 0C. The solution was stirred for 2 hours at 0 0C and then for 1 hour at ambient temperature. A solution of 4-formylmorpholine (2.1 ml, 20.3 mmol) in tetrahydrofuran (25 ml) was added dropwise and the solution stirred at ambient temperature for 1 hour. The solution was poured into water and extracted with ethyl acetate. The combined organic extracts were washed with brine, dried over magnesium sulphate, filtered and the solution concentrated under reduced pressure. The residue was purified by flash chromatography, eluting with 10 % ethyl acetate in isohexane, to give the title compound (3.0 g, 74 %); NMR Spectrum: (DMSO-d6) 2.44 (s, 3H), 8.19 (s, IH), 8.73 (s, IH), 10.09 (s, IH).
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 3430-18-0, 2,5-Dibromo-3-methylpyridine.
