What is Benzoyl isothiocyanate?
Chemical properties
CLEAR YELLOW TO ORANGE-BROWN LIQUID
The Uses of Benzoyl isothiocyanate
Benzoyl isothiocyanate has been used in the preparation of:
- 1-benzoyl-3-(5-chloro-2-hydroxyphenyl)thiourea, new thiourea derivative
- guanine
Purification Methods
Distil the isothiocyanate over a small amount of P2O5, whereby the distillate crystallises in prisms. It is readily hydrolysed by H2O to give benzamide and benzoylurea, but with NH3 it gives benzoylurea m 210o which can be recrystallised from EtOH.
