| NIST chemical information | Information provided by: webbook.nist.gov (external link) |
| Uses | 4-ethoxybenzoyl chloride is a pharmaceutical and chemical synthesis intermediate, which can be prepared from p-ethoxybenzoic acid as the reaction raw material and reacted with thionyl chloride. It can be used to prepare fluorescent dichroic dyes. |
| preparation | 0.5g of p-ethoxybenzoic acid, 5 mLCHCl3, 1.5 mLSOCl2 and 0.25mL DMF were added to 25mL double-mouth reaction bottles respectively, stirred at room temperature for 5 hours, then the solvent was removed under reduced pressure to obtain crude product 4-ethoxybenzoyl chloride. |
