Chemical Structure

(R,E)-N-((1S,5S,6R)-5-Hydroxy-5-((1E,3E,5E)-7-((2-hydroxy-5-oxocyclopent-1-en-1-yl)amino)-7-oxohepta-1,3,5-trien-1-yl)-2-oxo-7-oxabicyclo[4.1.0]hept-3-en-3-yl)-2,4-dimethyloct-2-enamide CAS 139023-58-8 chemical structure

Description

The molecular framework of (R,E)-N-((1S,5S,6R)-5-Hydroxy-5-((1E,3E,5E)-7-((2-hydroxy-5-oxocyclopent-1-en-1-yl)amino)-7-oxohepta-1,3,5-trien-1-yl)-2-oxo-7-oxabicyclo[4.1.0]hept-3-en-3-yl)-2,4-dimethyloct-2-enamide (C28H34N2O7) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).

(R,E)-N-((1S,5S,6R)-5-Hydroxy-5-((1E,3E,5E)-7-((2-hydroxy-5-oxocyclopent-1-en-1-yl)amino)-7-oxohepta-1,3,5-trien-1-yl)-2-oxo-7-oxabicyclo[4.1.0]hept-3-en-3-yl)-2,4-dimethyloct-2-enamide (CAS 139023-58-8) is a high-purity analytical reference standard with the molecular formula C28H34N2O7 and a molecular weight of 510.58 g/mol.

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.
