Chemical Structure

1H-imidazole-1-acetic acid, 2-nitro-, methyl ester 22813-31-6 InChI=1/C6H7N3O4/c1-13-5(10)4-8-3-2-7-6(8)9(11)12/h2-3H,4H2,1H methyl (2-nitro-1H-imidazol-1-yl)acetate CAS 22813-31-6 chemical structure

Description

The molecular framework of 1H-imidazole-1-acetic acid, 2-nitro-, methyl ester 22813-31-6 InChI=1/C6H7N3O4/c1-13-5(10)4-8-3-2-7-6(8)9(11)12/h2-3H,4H2,1H methyl (2-nitro-1H-imidazol-1-yl)acetate (C6H11N3O4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
