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 2-Dicyclohexylphosphino-2 inverted exclamation marka,4 inverted exclamation marka,6 inverted exclamation marka-triisopropylbiphenyl gold(I) chloride 854045-94-6 Chloro[2-dicyclohexyl(2 inverted exclamation marka,4 inverted exclamation marka,6 inverted exclamation marka-trisopropylbiphenyl)phosphine]gold(I) XPhos AuCl.
2-Dicyclohexylphosphino-2 inverted exclamation marka,4 inverted exclamation marka,6 inverted exclamation marka-triisopropylbiphenyl gold(I) chloride 854045-94-6 Chloro[2-dicyclohexyl(2 inverted exclamation marka,4 inverted exclamation marka,6 inverted exclamation marka-trisopropylbiphenyl)phosphine]gold(I) XPhos AuCl (CAS 854045-94-6) is a high-purity analytical reference standard with the molecular formula C33H61PAuCl and a molecular weight of 721.25 g/mol.
Based on its molecular formula C33H61PAuCl, 2-Dicyclohexylphosphino-2 inverted exclamation marka,4 inverted exclamation marka,6 inverted exclamation marka-triisopropylbiphenyl gold(I) chloride 854045-94-6 Chloro[2-dicyclohexyl(2 inverted exclamation marka,4 inverted exclamation marka,6 inverted exclamation marka-trisopropylbiphenyl)phosphine]gold(I) XPhos AuCl contains organophosphorus functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 721.25 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.
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.
