12,16-Dioxatetracyclo[11.2.1.0^{2,11}.0^{3,8}]hexadeca-2(11),3(8),4,6,9-pentaene (CAS 22794-75-8) is a high-purity analytical reference standard with the molecular formula C14H12O2 and a molecular weight of 212.24 g/mol.
12,16-Dioxatetracyclo[11.2.1.0^{2,11}.0^{3,8}]hexadeca-2(11),3(8),4,6,9-pentaene (C14H12O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
