Chemical Structure

(3AR,4R,5R,6aS)-5-hydroxy-4-((S)-3-hydroxy-5-phenylpentyl)hexahydro-2H-cyclopenta[b]furan-2-one CAS 145773-21-3 chemical structure

Description

The occurrence of (3AR,4R,5R,6aS)-5-hydroxy-4-((S)-3-hydroxy-5-phenylpentyl)hexahydro-2H-cyclopenta[b]furan-2-one is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3AR,4R,5R,6aS)-5-hydroxy-4-((S)-3-hydroxy-5-phenylpentyl)hexahydro-2H-cyclopenta[b]furan-2-one (CAS 145773-21-3) is a high-purity analytical reference standard with the molecular formula C18H24O4 and a molecular weight of 304.38 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, (3AR,4R,5R,6aS)-5-hydroxy-4-((S)-3-hydroxy-5-phenylpentyl)hexahydro-2H-cyclopenta[b]furan-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
