Application

N-Phenylhydroxylamine can be used as a starting material for the synthesis of:
  • 2-alkylindoles by treating with aliphatic terminal alkynes using gold catalyst via sequential 3,3-rearrangements and cyclodehydrations.
  • Isoxazolidines by reacting with aldehydes and α, β-unsaturated aldehydes via a three-component one-pot catalytic reaction.
  • Tetrahydro-1,2-oxazines by treating with an aldehyde and cyclopropane via homo 3+2 dipolar cycloaddition reaction.

Phenylhydroxylamine (PHA) and its derivatives such as monomethyl (2-Me, 3-Me, 4-Me) and dimethyl (2,3-diMe, 2,4-diMe, 2,5-diMe, 2,6-diMe, 3,4-diMe, 3,5-diMe) were tested for their mutagenicity and for their inducing ability to inactivate transforming DNA. All these compounds except PHA and 3,5-diMePHA

Previous studies have shown that incubation of rat red blood cells in vitro with phenylhydroxylamine (50-300 microM) induces rapid splenic sequestration of the red cells on reintroduction to isologous rats. EPR and the spin trapping agent, 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), were utilized

Cigarette smoking is associated with plasmatic hypercoagulability, and carbon monoxide has been demonstrated to enhance coagulation by binding to a fibrinogen-bound heme. Our objective was to design and test a redox-based method to detect carboxyhemefibrinogen. Normal, pooled, citrated plasma was
