[μ-[1,2-Ethanediylbis[diphenylphosphine]-P:P']]bis(1-thio-β-D-glucopyranosato-S)digold CAS 105177-81-9

Description

[μ-[1,2-Ethanediylbis[diphenylphosphine]-P:P']]bis(1-thio-β-D-glucopyranosato-S)digold (CAS 105177-81-9) is a high-purity analytical reference standard with the molecular formula C38H46Au2O10P2S2 and a molecular weight of 1182.78 g/mol.

Owing to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, [μ-[1,2-Ethanediylbis[diphenylphosphine]-P:P']]bis(1-thio-β-D-glucopyranosato-S)digold is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1182.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
