Related Products of 66572-56-3, 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 66572-56-3, name is 2-Bromoisonicotinic acid. This compound has unique chemical properties. The synthetic route is as follows.

2-Bromoisonicotinic acid (2.02 g, 10 mmol) was dissolved in DMF (80 mL) under argon. Pd(PPh3)4 (0.6 g, 0.52 mmol) was added, and the reaction mixture was stirred at room temperature for 15 min. Na2CO3 (aq. 2N, 40 mL) was then added, followed by the addition of phenylboronic acid (1.67 g, 13.7 mmol). The reaction mixture was heated at 95C (18 h), cooled to room temperature and filtered through a celite pad. Water (80 mL) was added, and the mixture was acidified with HCl (2 N) to pH = 4. The precipitate was collected via filtration and rinsed with water (2 x 7 mL). The crude product was recrystallized from 2-methoxylethanol to give 2- phenylisonicotinic acid as a grey solid (1.2 g). 1HNMR (DMSO-d6, 400 MHz): delta 7.51 (m, 3H), 7.78 (d, J=4.8 Hz, 1H), 8.13 (t, J=1.6 Hz, 2H), 8.29 (s, 1H), 8.85 (d, j=4.8 Hz, 1H), 13.73 (bs, 1H).

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 66572-56-3, 2-Bromoisonicotinic acid.
