The occurrence of (3aR,4R,5R,6aS)-4-((E)-4-(3-Chlorophenoxy)-3-oxobut-1-en-1-yl)-2-oxohexahydro-2H-cyclopenta[b]furan-5-yl [1,1'-biphenyl]-4-carboxylate is closely related to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3aR,4R,5R,6aS)-4-((E)-4-(3-Chlorophenoxy)-3-oxobut-1-en-1-yl)-2-oxohexahydro-2H-cyclopenta[b]furan-5-yl [1,1'-biphenyl]-4-carboxylate (CAS 54324-79-7) is a high-purity analytical reference standard with the molecular formula C30H25ClO6 and a molecular weight of 516.97 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, (3aR,4R,5R,6aS)-4-((E)-4-(3-Chlorophenoxy)-3-oxobut-1-en-1-yl)-2-oxohexahydro-2H-cyclopenta[b]furan-5-yl [1,1'-biphenyl]-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 516.97 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
