(11b<I>R</I>,11′b<I>R</I>)-4,4′--(9,9-二甲基-9<I>H</I>-氧杂蒽-4,5-二基)双-二萘并[2,1-<I>d</I>:1′, 2′-f][1,3,2]二磷杂庚英 (CAS 349114-63-2), molecular formula C55H88O5P2 and molecular weight 891.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (11b<I>R</I>,11′b<I>R</I>)-4,4′--(9,9-二甲基-9<I>H</I>-氧杂蒽-4,5-二基)双-二萘并[2,1-<I>d</I>:1′, 2′-f][1,3,2]二磷杂庚英 (C55H88O5P2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 891.23 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
