CAS 83286-56-0

Phenyl-D5 isocyanate, with the CAS number 83286-56-0, is a deuterated derivative of phenyl isocyanate. It features a phenyl group attached to an isocyanate functional group, where the hydrogen atoms on the phenyl ring are replaced by deuterium, a stable isotope of hydrogen. This substitution enhances its utility in various analytical applications, particularly in NMR spectroscopy, where deuterated compounds provide clearer spectra due to reduced background signals. Phenyl-D5 isocyanate is typically a colorless to pale yellow liquid with a characteristic odor. It is known for its reactivity, particularly in forming ureas and carbamates through nucleophilic addition reactions with amines and alcohols. As with other isocyanates, it is important to handle phenyl-D5 isocyanate with care due to its potential toxicity and irritant properties. Proper safety measures, including the use of personal protective equipment and working in a well-ventilated area, are essential when working with this compound.
