white or greyish-beige crystalline powder | [Uses]
4'-Chloroacetanilide is used in pharmaceutical preparations, using PGC column. And also used in the synthesis of alprazolam. | [Definition]
ChEBI: Acetamide substituted on nitrogen by a para-chlorophenyl group. | [Synthesis Reference(s)]
Tetrahedron, 52, p. 8863, 1996 DOI: 10.1016/0040-4020(96)00433-4 | [General Description]
4′-Chloroacetanilide is the main impurity present in acetaminophen and has been quantitated by new high-performance liquid chromatography method using a mixed-mode reversed-phase/cation exchange stationary phase. | [Synthesis]
Preparation of p-chloroacetanilide: 113.5 mg (0.5 mmol) of 4-chlorophenyl diazonium tetrafluoroborate, 0.1 mmol of cuprous iodide, 0.5 mmol of potassium phosphate with 1.0 mmol of water were added to a Schlenk tube under nitrogen and 1 mL of acetonitrile | [Purification Methods]
Crystallise the anilide from EtOH or aqueous EtOH. [Beilstein 12 IV 1178.] |
