3-Methoxy-4-[(3-nitropyridin-2-yl)oxy]benzaldehyde (CAS 700849-38-3), molecular formula C13H10N2O5 and molecular weight 274.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Methoxy-4-[(3-nitropyridin-2-yl)oxy]benzaldehyde (C13H10N2O5) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
