2,3,4-TRICHLOROANILINE Chemical Properties,Usage,Production

Uses

2,3,4-Trichloroaniline is used as a reagent in the synthesis of SYP-10913 and SYP-11277, compounds that exhibit potent acaricidal activity. It also used as a reagent in the synthesis of dioxin-like monofluorinated polychlorinated biphenyls (PCBs) for the use as internal standards in PCB analysis.

Purification Methods

Crystallise the aniline from ligroin. The acetanilide has m 120-122o (from EtOH or *C6H6). [Beilstein 12 H 626.]
