| Use | is useful as an intermediate in organic synthesis. |
| production method | is obtained by esterification of p-nitrobenzoic acid with methanol. The mixture of p-nitrobenzoic acid, methanol and sulfuric acid was heated under reflux for 4H, and then poured into ice water to precipitate crystals. Filtration, washing with water to remove the acid, and then separately methanol and water recrystallization once, that is, the finished product. |
