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 2-((2R,4aR,6R,7R,8R,8aS)-6,8-bis(benzyloxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxin-7-yl)isoindoline-1,3-dione.
2-((2R,4aR,6R,7R,8R,8aS)-6,8-bis(benzyloxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxin-7-yl)isoindoline-1,3-dione (CAS 191482-37-8), molecular formula C35H31NO7 and molecular weight 577.62 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C35H31NO7, 2-((2R,4aR,6R,7R,8R,8aS)-6,8-bis(benzyloxy)-2-phenylhexahydropyrano[3,2-d][1,3]dioxin-7-yl)isoindoline-1,3-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 577.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
