Related Products of 846021-26-9, 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 846021-26-9, name is 2-Amino-6-methylnicotinic acid. This compound has unique chemical properties. The synthetic route is as follows.

2-Amino-6-methyl nicotinic acid (3.04 g) was suspended in N,N-dimethylformamide (60 mL), and potassium carbonate (5.53 g) was added to the suspension, followed by stirring at 40 C. for 30 minutes. Solution (I) was dropwise added to the resulting suspension, followed by stirring with heating at 80 C. for 2 hours. The reaction solution was cooled to room temperature, and the N,N-dimethylformamide (45 mL, 64%) was removed by distillation under reduced pressure. Iced water (100 mL) was added to the residue, followed by stirring at room temperature for minutes. Precipitated crystals were collected by filtration and were dried to give 6.42 g (yield: 92%) of the target product (Compound 4 shown in Table 1). According to purity analysis by liquid chromatography, the purity of thus obtained target product was high, 99.1%. A melting point thereof was 94 C. to 96 C.10058] ?H-NMR (CDC13) oeppm: 2.33 (3H, s), 2.40 (3H, s), 5.27 (2H, s), 6.08-6.82 (2H, br), 6.44 (1H, d), 6.90-7.00 (5H, m), 7.14 (2H, d), 7.37 (2H, d), 8.02 (1H, d)

According to the analysis of related databases, 846021-26-9, the application of this compound in the production field has become more and more popular.
