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.
