Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 204.13 g/mol gives 5-Oxo-1,3-dioxolane-4,4-diacetic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Oxo-1,3-dioxolane-4,4-diacetic Acid (CAS 144-16-1), molecular formula C7H8O7 and molecular weight 204.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Oxo-1,3-dioxolane-4,4-diacetic Acid (C7H8O7) is characterized by a carbohydrate-derived structure. 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.
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.
