Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S)-1-(Diphenylphosphino)-2-[(1R)-1-(diphenylphosphino)ethyl]ferrocene.
(1S)-1-(Diphenylphosphino)-2-[(1R)-1-(diphenylphosphino)ethyl]ferrocene (CAS 155941-31-4) is a high-purity analytical reference standard with the molecular formula C31H32P2C5H10Fe and a molecular weight of 592.52 g/mol.
Structurally, (1S)-1-(Diphenylphosphino)-2-[(1R)-1-(diphenylphosphino)ethyl]ferrocene (C31H32P2C5H10Fe) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 592.52 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.
