Chemical Structure
Description
Phosphine, 1,1′-[(1S)-6,6′-dimethoxy[1,1′-biphenyl]-2,2′-diyl]bis[1,1-di-2-naphthalenyl- (CAS 849239-14-1), molecular formula C54H40O2P2 and molecular weight 782.84 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Phosphine, 1,1′-[(1S)-6,6′-dimethoxy[1,1′-biphenyl]-2,2′-diyl]bis[1,1-di-2-naphthalenyl- (C54H40O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 35.0, corresponding to approximately 35 ring(s) or double-bond equivalent(s). With a molecular weight of 782.84 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
