Structurally, (R,R)-(-)-1,2-Bis[(2-methoxyphenyl)(phenyl)phosphino]ethane 55739-58-7 (-)-DIPAMP;(1R,2R)-BIS[(2-METHOXYPHENYL)PHENYLPHOSPHINO]ETHANE;(R,R)-(-)-1,2-BIS[(2-METHOXYPHENYL)(PHENYL)PHOSPHINO]ETHANE;(R,R)-1,2-BIS[(2-METHOXYPHENYL)PHENYLPHOSPHINO]ETHANE;(R,R)-1,2-BIS[(O-METHOXYPHENYL)PHENYLPHOSPHINO]ETHANE;(R,R)-1,2-ETHANEDIYLBIS[(2-METHOXYPHENYL)PHENYLPHOSPHINE];(R,R)-DIPAMP;(R,R)-ETHYLENEBIS[(2-METHOXYPHENYL)PHENYLPHOSPHINE];[(1R,2R)-(-)-BIS[(2-METHOXYPHENYL)PHENYLPHOSPHINO]ETHANE] SC11064 (C28H52O2P2) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 482.66 g/mol, it falls into the moderately-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.
