Chemical Structure

4,5,5-Triphenyldihydrofuran-2(3H)-one CAS 57697-68-4 chemical structure

Description

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.

CATO supplies 4,5,5-Triphenyldihydrofuran-2(3H)-one (CAS 57697-68-4), a certified reference material (molecular formula C22H18O2, MW 314.38 g/mol) for analytical method development and quality control.

Structurally, 4,5,5-Triphenyldihydrofuran-2(3H)-one (C22H18O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 314.38 g/mol, it falls into the moderately-high-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
