4,4'-(Pentane-1,5-diylbis(oxy))dibenzaldehyde (CAS 77355-01-2) is a high-purity analytical reference standard with the molecular formula C19H20O4 and a molecular weight of 312.36 g/mol.
4,4'-(Pentane-1,5-diylbis(oxy))dibenzaldehyde (C19H20O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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.
