4-Nitrophenol is used as a precursor to prepare phenetidine, acetophenetidne and pH indicator. Its carboxylate ester derivatives are involved as an active component for the construction of amide moieties in peptide synthesis. It is used as an intermediate in the synthesis of paracetamol and N-acetyl-p-aminophenol dyestuffs.
Acid-base indicator: pH 5.6 - 7.6.
Forms active esters with N-protected amino acids, useful in peptide synthesis; see, for example: J. Org. Chem., 62, 1356 (1997). For peptide reagents, see Appendix 6.
Suzuki-type coupling of the triflate with various arylboronic acids gives biaryl derivatives: Tetrahedron, 45, 6679 (1984). For an example of Stille coupling of the triflate with an arylstannane, catalyzed by trans-Dichlorobis(triphenylphosphine)palladium(II), 10491, see: Org. Synth. Coll., 9, 553 (1998)./n
