Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Pyridin-4-ylethynyl)(triphenylphosphoranyl)gold.
CATO supplies (Pyridin-4-ylethynyl)(triphenylphosphoranyl)gold (CAS 825628-22-6), a certified reference material (molecular formula C25H20AuNP, MW 562.37 g/mol) for analytical method development and quality control.
(Pyridin-4-ylethynyl)(triphenylphosphoranyl)gold (C25H20AuNP) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), (Pyridin-4-ylethynyl)(triphenylphosphoranyl)gold 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.
