Synthetic Route of 887707-23-5, 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 887707-23-5, name is 2-Hydroxy-5-iodo-3-(trifluoromethyl)pyridine. This compound has unique chemical properties. The synthetic route is as follows.
Step B. 2-chloro-5-iodo-3-(trifluoromethyl)pyridine A suspension of 5-iodo-3-(trifluoromethyl)pyridin-2-ol (3.0 g, 10.4 mmol) in POCI3 (8 mL) was heated at 100 C overnight. After cooling down to room temperature, the mixture was poured into ice (50 g). The resulting aqueous layer was neutralized by Na2C03 and extracted with EtOAc (70 mL x 2). The extracts were combined, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by silica gel chromatography using petroleum ether:EtOAc (100: 1-4: 1) as eluting solvents to afford 2- chloro-5-iodo-3-(trifluoromethyl)pyridine as a white solid (2.0 g, 63%). 1H NMR (500 MHz, CDC13) delta (ppm) 8.78 (d, / = 2.0 Hz, 1H), 8.28 (d, / = 2.0 Hz, 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 887707-23-5, 2-Hydroxy-5-iodo-3-(trifluoromethyl)pyridine.
