Description

CATO supplies 3-Di-i-propylphosphoranylidene-2-(N,N-dimethylamino)-1H-indene(1,5-cyclooctadiene)rhodium(I) (CAS 540492-55-5), a certified reference material (molecular formula C19H32NPRhC8H12, MW 516.54 g/mol) for analytical method development and quality control.

Structurally, 3-Di-i-propylphosphoranylidene-2-(N,N-dimethylamino)-1H-indene(1,5-cyclooctadiene)rhodium(I) (C19H32NPRhC8H12) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 516.54 g/mol, it falls into the moderately-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).

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), 3-Di-i-propylphosphoranylidene-2-(N,N-dimethylamino)-1H-indene(1,5-cyclooctadiene)rhodium(I) 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.
