4-Nitrophenyl isocyanate

Description:

4-Nitrophenyl isocyanate is an organic compound characterized by its isocyanate functional group attached to a nitrophenyl moiety. It typically appears as a yellow crystalline solid and is known for its reactivity, particularly in nucleophilic addition reactions due to the presence of the isocyanate group. This compound is soluble in organic solvents such as acetone and ether but is generally insoluble in water. It has applications in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. The presence of the nitro group enhances its electrophilic character, making it useful in coupling reactions. However, it is important to handle 4-nitrophenyl isocyanate with care, as it can be toxic and irritant, posing health risks upon exposure. Proper safety measures, including the use of personal protective equipment and working in a well-ventilated area, are essential when working with this compound.

4-Nitrophenyl isocyanate

CAS: 100-28-7

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.
