Chemical Structure
Description
The molecular framework of Diethyl 2-oxaspiro[3.3]heptane-6,6-dicarboxylate (C12H18O5) 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).
Diethyl 2-oxaspiro[3.3]heptane-6,6-dicarboxylate (CAS 26593-41-9) is a high-purity analytical reference standard with the molecular formula C12H18O5 and a molecular weight of 242.27 g/mol.
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.
