Chemical Structure
Description
Gold, (2-phenylethenyl)(triphenylphosphine)-, (Z)- (CAS 57947-31-6), molecular formula C26H22AuP and molecular weight 562.39 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Gold, (2-phenylethenyl)(triphenylphosphine)-, (Z)- (C26H22AuP) contains organophosphorus functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 562.39 g/mol, it falls into the moderately-high-molecular-weight range. 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), Gold, (2-phenylethenyl)(triphenylphosphine)-, (Z)- 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.
