4-Nitrophenyl isocyanate Chemical Properties,Uses,Production

Chemical Properties

yellow crystalline solid

Uses

4-Nitrophenyl isocyanate is used as pharmaceutical intermediates. 4-Nitrophenyl isocyanate was used in the synthesis of 2-(5-methyl-3,4-diphenyl-1H-pyrrole-2-carbonyl)-N-(4-nitrophenyl)hydrazinecarboxamide.

Safety Profile

A poison by intraperitoneal route.Moderately toxic by ingestion. When heated todecomposition it emits toxic vapors of NOx.

Purification Methods

Distil the isocyanate in a vacuum, and/or recrystallise it from pet ether (b 28-38o), *C6H6/pet ether (m 58o) or CCl4 (m 56-57o). [Beilstein 12 H 725, 12 III 1630.]
