General description
Phenyl isocyanate reacts with ethyl alcohol to yield ethyl α,γ-diphenylallophanate and trace of phenyl isocyanate dimer.
Application
Phenyl isocyanate (PhNCO) can undergo addition reaction with primary nitroparaffins in the presence of a tertiary alkyl amine catalyst to form sym-disubstituted urea and furoxane. It can also react with cyclohexadienones to form vicinal diamine-containing heterocycle derivatives.
Phenyl isocyanate was used to prepare chemically modified cellulose paper. It was used in the synthesis of functionalized graphene oxide nanoplatelets.

There are few studies on phenylisocyanate (PhI) exposure, although there are studies indicating that PhI is a very potent chemical sensitizer. The aim of this study was to evaluate aniline in urine and plasma as possible biomarkers of exposure to
