trans-Chloro(ethylene)bis(triphenylphosphine)rhodium CAS 74006-69-2

Description

Compared with other compounds in its class, the molecular weight of 690.98 g/mol gives trans-Chloro(ethylene)bis(triphenylphosphine)rhodium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

trans-Chloro(ethylene)bis(triphenylphosphine)rhodium (CAS 74006-69-2), molecular formula C38H34ClP2Rh and molecular weight 690.98 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to organophosphorus functionality, chlorine substitution, a polycyclic aromatic system, trans-Chloro(ethylene)bis(triphenylphosphine)rhodium is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 690.98 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), trans-Chloro(ethylene)bis(triphenylphosphine)rhodium 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.
