Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 13194-68-8, name is 4-Iodo-2-methylaniline, This compound has unique chemical properties. The synthetic route is as follows., Application In Synthesis of 4-Iodo-2-methylaniline
EXAMPLE 3; Synthesis of (3); A flask is charged with 100 mmol of boric acid followed by 6N HCl solution to adjust the reaction solution to a pH of 2. Once the salt dissolves, 20 mmol of 4-iodo-2-methylaniline is added to the reaction solution, followed by enough ice to reduce solution temperature to 0 C. In a separate flask, 20 mmol of sodium nitrite (NaNO2) is dissolved in ice water. The NaNO2 solution is added drop-wise with constant stirring to the 4-iodo-2-methylaniline solution. The pH of the reaction solution is maintained by addition of 6N HCl. After the NaNO2 solution addition is complete, ice is added to maintain the 0 C. reaction temperature. A 3rd flask is charged with 20 mmol of p-cresol, water and 2.5 N NaOH (20 mmol), which is then added drop wise to the ice cooled reaction with constant stirring. The reaction mixture is allowed to stir for 15 min at pH 2.0-2.5. NaOH (2.5 N) is then added in small aliquots to the reaction solution to increase the pH to 8.5. The reaction solution is allowed to warm to room temperature. Dibasic sodium phosphate solution (100 mmol) is added and the pH is adjusted to 6.0 with 6 N HCl. The product is filtered, rinsed with ice water and air dried. The product is purified by column chromatography to yield 2-(4-iodo-2-methyl-phenylazo)-4-methyl-phenol (3).
According to the analysis of related databases, 13194-68-8, the application of this compound in the production field has become more and more popular.
