Application | 3, 4-dihydroxy-5-nitrobenzaldehyde can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly used in laboratory research and development and chemical production process. |
preparation | 3-ethoxy-4-hydroxy-5-nitrobenzaldehyde: at 5-10 °c, to a solution of 3-ethoxy-4-hydroxybenzaldehyde (83.0G) in dichloromethane (400 ml) was added with stirring (at a rate of approximately 1.5 mL/min). Fuming nitric acid (22.0). Thereafter, the mixture was stirred at 3 °c for 30 minutes and then filtered. The product was washed with methylene chloride and water and dried under vacuum at 50 °c to give 77.8G (73.7%) of product. |
