9-Oxo-3-oxabicyclo[3.3.1]nonane-7-carboxylic acid (CAS 1333639-36-3) is a high-purity analytical reference standard with the molecular formula C9H12O4 and a molecular weight of 184.19 g/mol.
The molecular framework of 9-Oxo-3-oxabicyclo[3.3.1]nonane-7-carboxylic acid (C9H12O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
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.
