(S)-7,7′-Bis[di(3,5-xylyl)phosphino]-3,3′,4,4′-tetrahydro-4,4′-dimethyl-8,8′-bi(2H-1,4-benzoxazine) CAS 649559-70-6

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (S)-7,7′-Bis[di(3,5-xylyl)phosphino]-3,3′,4,4′-tetrahydro-4,4′-dimethyl-8,8′-bi(2H-1,4-benzoxazine) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 776.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

(S)-7,7′-Bis[di(3,5-xylyl)phosphino]-3,3′,4,4′-tetrahydro-4,4′-dimethyl-8,8′-bi(2H-1,4-benzoxazine) (CAS 649559-70-6), molecular formula C50H54N2O2P2 and molecular weight 776.92 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
