Description
Compared with other compounds in its class, the molecular weight of 633.65 g/mol gives (11bS)-N-((S)-1-(2-(diphenylphosphanyl)phenyl)ethyl)-N-methyldinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(11bS)-N-((S)-1-(2-(diphenylphosphanyl)phenyl)ethyl)-N-methyldinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine (CAS 913265-33-5), molecular formula C41H33NO2P2 and molecular weight 633.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (11bS)-N-((S)-1-(2-(diphenylphosphanyl)phenyl)ethyl)-N-methyldinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 633.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
