p-Tolyl isocyanate Usage And Synthesis

Chemical Properties

CLEAR SLIGHTLY BROWN LIQUID

Uses

p-Tolyl isocyanate was used to study the catalytic role of supported Rhodium(I) complex toward the reductive carbonylation of nitrobenzene in DMF medium.

Definition

ChEBI: An isocyanate comprising a benzene core with isocyanato and methyl substituents para to each other.

General Description

p-Tolyl isocyanate reacts with human serum albumin to form antigen which helps in detecting IgE antibodies in workers hypersensitive to toluene diisocyanate.

Hazard

A Poison by inhalation. Moderately toxic by ingestion.
