4-Hydroxy-6-phenethyl-2H-pyran-2-one CAS 33253-32-6

Description

Compared with other compounds in its class, the molecular weight of 216.23 g/mol gives 4-Hydroxy-6-phenethyl-2H-pyran-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Hydroxy-6-phenethyl-2H-pyran-2-one (CAS 33253-32-6), molecular formula C13H12O3 and molecular weight 216.23 g/mol, is a CATO reference standard with documented purity and traceability.

4-Hydroxy-6-phenethyl-2H-pyran-2-one (C13H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
