Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 710.88 g/mol gives 4-Phenyl-2,5-dihydrofuran-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Phenyl-2,5-dihydrofuran-2-one (CAS 1575-47-9), molecular formula C36H50N6O7S and molecular weight 710.88 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Phenyl-2,5-dihydrofuran-2-one (C36H50N6O7S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
