P-BROMOPHENYL HYDRAZINE Usage And Synthesis

Uses

In preparation of indoleacetic acid derivatives; in the study of transosazonation of sugar phenylosazones.

Purification Methods

Crystallise the hydrazine from H2O. The hydrochloride crystallises from EtOH/H2O with m 213-214o, and the tosylate has m 212o (from EtOH). [Beilstein 15 H 434, 15 I 117, 15 II 160, 15 III 289, 15 IV 282.]
