VA926Z93IF 42454-06-8 5-Hydroxy-2-nitrobenzaldehyde Benzaldehyde, 5-hydroxy-2-nitro- 4-08-00-00250 (Beilstein Handbook Reference) BRN 1910196 EINECS 255-832-9 3-Formyl-4-nitrophenol NSC 93899 UNII-VA926Z93IF (CAS 42454-06-8), molecular formula C7H11NO4 and molecular weight 173.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of VA926Z93IF 42454-06-8 5-Hydroxy-2-nitrobenzaldehyde Benzaldehyde, 5-hydroxy-2-nitro- 4-08-00-00250 (Beilstein Handbook Reference) BRN 1910196 EINECS 255-832-9 3-Formyl-4-nitrophenol NSC 93899 UNII-VA926Z93IF (C7H11NO4) 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).
