CAS 100-28-7: 4-Nitrophenyl isocyanate

4-Nitrophenyl isocyanate (4NPC) is an alkynyl group that reacts with nitrite ion to form the reactive intermediate 4-nitrophenyl isocyanate ion. This reaction can be used to synthesize fatty acids by reacting with carbonyl groups. The activation energies for this reaction are dependent on the type of amines and fatty acid used. Analytical chemistry can be used to determine the analytical method for determining the concentration of nitrite ions in a solution containing 4NPC and hydrogen fluoride.

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.
