Chemical Structure

(R,R)-NORPHOS-Rh CAS 521272-85-5 chemical structure

Description

Structurally, (R,R)-NORPHOS-Rh (C33H34P2RhC8H12BF3F) contains organophosphorus functionality, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 790.48 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).

(R,R)-NORPHOS-Rh (CAS 521272-85-5) is a high-purity analytical reference standard with the molecular formula C33H34P2RhC8H12BF3F and a molecular weight of 790.48 g/mol.

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.
