Chemical Structure
Description
The occurrence of (R)-7'-(Bis(3,5-di-tert-butylphenyl)phosphanyl)-2,2',3,3'-tetrahydro-1,1'-spirobi[inden]-7-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-7'-(Bis(3,5-di-tert-butylphenyl)phosphanyl)-2,2',3,3'-tetrahydro-1,1'-spirobi[inden]-7-amine (CAS 1219025-18-9), molecular formula C45H58NP and molecular weight 643.92 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, (R)-7'-(Bis(3,5-di-tert-butylphenyl)phosphanyl)-2,2',3,3'-tetrahydro-1,1'-spirobi[inden]-7-amine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 643.92 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.
As a certified reference material (CRM), (R)-7'-(Bis(3,5-di-tert-butylphenyl)phosphanyl)-2,2',3,3'-tetrahydro-1,1'-spirobi[inden]-7-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
