Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 533.68 g/mol gives (1R)-(2'-(Dimethylamino)-5,5',6,6',7,7',8,8'-octahydro-[1,1'-binaphthalen]-2-yl)di-p-tolylphosphine oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (1R)-(2'-(Dimethylamino)-5,5',6,6',7,7',8,8'-octahydro-[1,1'-binaphthalen]-2-yl)di-p-tolylphosphine oxide (CAS 328074-74-4), a certified reference material (molecular formula C36H40NOP, MW 533.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, (1R)-(2'-(Dimethylamino)-5,5',6,6',7,7',8,8'-octahydro-[1,1'-binaphthalen]-2-yl)di-p-tolylphosphine oxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 533.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
