2-Methoxy-5-(pyrimidin-5-yl)benzaldehyde (CAS 190271-69-3), molecular formula C12H10N2O2 and molecular weight 214.22 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methoxy-5-(pyrimidin-5-yl)benzaldehyde (C12H10N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
