Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Gold, dimethyl(phenylethynyl)(triphenylphosphine)-, (SP-4-3)-.
CATO supplies Gold, dimethyl(phenylethynyl)(triphenylphosphine)-, (SP-4-3)- (CAS 110320-16-6), a certified reference material (molecular formula C28H26AuP, MW 590.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C28H26AuP, Gold, dimethyl(phenylethynyl)(triphenylphosphine)-, (SP-4-3)- contains organophosphorus functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 590.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
