The study of the oxidation of various proteins necessitates scrutiny of the amino acid sequence. Since methionine (Met) and tyrosine (Tyr) are easily oxidized, peptides that contain these amino acids are frequently studied using a variety of oxidatio

The title compound, C9H10N2O4, crystallizes with a disordered nitro group in twinned crystals. Both the methoxy group and the acetamide groups are nearly coplanar with the phenyl ring, and the C—N—C—O torsion angle [0.2 (4)°] is also insignifi

The title compound, C8H8N2O4, differs in its degree of planarity from the 3-nitro isomer and also in its hydrogen-bonding pattern. Its NH group forms an intramolecular hydrogen bond to a nitro oxygen atom, and its OH group forms an intermolecular hyd
