(Z)-7-[(1R)-3alpha,5alpha-Dihydroxy-2beta-[(E)-2-[2-[(4-Fluorophenoxy)Methyl]-1,3-Dioxolan-2-Yl]Ethenyl]Cyclopentan-1alpha-Yl]-5-Heptenoic Acid Methyl Ester CAS 66176-11-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Z)-7-[(1R)-3alpha,5alpha-Dihydroxy-2beta-[(E)-2-[2-[(4-Fluorophenoxy)Methyl]-1,3-Dioxolan-2-Yl]Ethenyl]Cyclopentan-1alpha-Yl]-5-Heptenoic Acid Methyl Ester.

(Z)-7-[(1R)-3alpha,5alpha-Dihydroxy-2beta-[(E)-2-[2-[(4-Fluorophenoxy)Methyl]-1,3-Dioxolan-2-Yl]Ethenyl]Cyclopentan-1alpha-Yl]-5-Heptenoic Acid Methyl Ester (CAS 66176-11-2), molecular formula C25H33FO7 and molecular weight 464.52 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (Z)-7-[(1R)-3alpha,5alpha-Dihydroxy-2beta-[(E)-2-[2-[(4-Fluorophenoxy)Methyl]-1,3-Dioxolan-2-Yl]Ethenyl]Cyclopentan-1alpha-Yl]-5-Heptenoic Acid Methyl Ester (C25H33FO7) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 464.52 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
