Chemical Structure

2-Phenyl-1,3-dioxan-5-one CAS 52941-82-9 chemical structure

Description

2-Phenyl-1,3-dioxan-5-one (CAS 52941-82-9), molecular formula C10H10O3H2O and molecular weight 196.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Phenyl-1,3-dioxan-5-one (C10H10O3H2O) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 196.20 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
