Description
CATO manufactures (3-Nitrophenyl)(triphenylphosphine)gold under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(3-Nitrophenyl)(triphenylphosphine)gold (CAS 87961-72-6), molecular formula C24H19AuNO2P and molecular weight 581.35 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C24H19AuNO2P, (3-Nitrophenyl)(triphenylphosphine)gold contains a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 581.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
