Description

Compared with other compounds in its class, the molecular weight of 298.33 g/mol gives 2-Oxo-1-oxa-spiro[4.5]decane-3,4-dicarboxylic acid diethyl ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Oxo-1-oxa-spiro[4.5]decane-3,4-dicarboxylic acid diethyl ester (CAS 134515-27-8), molecular formula C15H22O6 and molecular weight 298.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Oxo-1-oxa-spiro[4.5]decane-3,4-dicarboxylic acid diethyl ester (C15H22O6) 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 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
