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 7-((1R,2R,3R)-3-Hydroxy-2-((S,1E,5E)-3-hydroxyocta-1,5-dien-1-yl)-5-oxocyclopentyl)heptanoic acid.
7-((1R,2R,3R)-3-Hydroxy-2-((S,1E,5E)-3-hydroxyocta-1,5-dien-1-yl)-5-oxocyclopentyl)heptanoic acid (CAS 119008-22-9) is a high-purity analytical reference standard with the molecular formula C20H32O5 and a molecular weight of 352.47 g/mol.
The molecular framework of 7-((1R,2R,3R)-3-Hydroxy-2-((S,1E,5E)-3-hydroxyocta-1,5-dien-1-yl)-5-oxocyclopentyl)heptanoic acid (C20H32O5) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
